    Notes: In this investigation of the effect of a cylindrical boundary on a spherical particle suspended in a moving viscous fluid the pressure drop due to the motion of fluid past a stationary sphere and the drag on the sphere are independently measured, and the sphere- to-cylinder-diameter ratios varying from 0.1250 to 0.3125 are studied at different positions of eccentricity. The investigation shows that in the range of Reynolds numbers from 0.1 to 40.0, based on the approach velocity to the sphere and the diameter of the sphere, the pressure drop due to the presence of a sphere and the drag on it can be represented by a semiempirical relationship containing two terms. One term, owing to the effect of the cylindrical boundary, is derived theoretically from the creeping-motion equations which neglect inertial effects. The second term, owing to the inertial effects, is established from data on the drag coefficient of a sphere in on unbounded medium.

    Notes: In 1954 Becker found that the components of a gas mixture could be separated by allowing a jet of the gas mixture to expand in a low-pressure chamber. The heavier molecules would concentrate near the center of the jet and the lighter ones near the edge. Thus the jet could be split into two streams, one containing more of the heavy component and one containing more of the light component. In this paper it will be shown that this effect can be predicted from the kinetic theory of gases and that the predicted magnitude of the effect agrees favorably with the experimental data of Becker.

    Notes: Pressure-volume-temperature measurements have been made on methyl borate over the temperature range of 2257deg; to 300°C. and pressures of 30 to 200 atm. in a variable volume P-V-T bomb. Vapor-pressure measurements from 180°C. to the critical point have also been made with the same apparatus. The vapor-pressure data are presented in the form of the Antoine equation, and the P-V-T data together with the vapor-pressure data have been fitted to the Benedict-Webb-Rubin equation of state.

    Notes: The behavior of type-304 stainless steel in a forced-convection closed-loop lithium system was investigated over a wide range of temperatures and velocities. Fundamental information concerning the mechanism for mass transport has been obtained by examining solution and deposition effects along flat plates. The rate-determining process for solution is transport from the solid to the interface, whereas deposition rates are liquid-phase controlled.Liquid-phase mass transfer coefficients were correlated with a maximum deviation of approximately 15% by the use of von Kàrmàn's analysis of the turbulent boundary layer along a flat plate, combined with the Chilton-Colburn empirical modification of the Schmidt group. In contrast no adequate model is available for the prediction of solution rate constants which must be determined experimentally. Mean values of the solution rate constants ranged from 0.154 to 0.750 × 10-5 cm./sec. at temperatures from 510° to 612°C. These values are on the order of 103 smaller than corresponding liquid-phase mass transfer coefficients.

    Notes: The purpose of this investigation was to determine the interaction effect of one spherical particle upon another when both are falling in a viscous fluid. The velocities of two identical spheres, falling along the axis of a cylinder in a direction parallel to their line of centers, were measured experimentally as a function of the center-to-center distance between them at very low Reynolds numbers. The experimental results compared very well with theoretical studies found in the literature which predicted that two spheres will fall faster than one sphere.At Reynolds numbers greater than 0.25 the influence of inertial effects were studied for one end two spheres. The experimental results qualitatively confirmed the Oseen equations. A definite attraction between two spheres falling one above the other was observed; the inertial forces acted to slow down the lower sphere without affecting the upper one.

    Notes: New measurements of the volumes of liquid n-alkanes of 7, 9, 11, 13, 17, 20, 30, and 40 carbon atoms over a range of temperatures from 20° to 300°C. and pressures from 0 to 4,000 kg./sq. cm. have been made. These volume measurements are here reduced to compressions (volpT)/(vol°T), and the accuracy of the measurements has been determined. Analysis of the data for n-heptane and n-eicosane shows that the order of accuracy of the compressions of each of these compounds appears to be approximately 3 parts in 10,000. Evaluation of random multiple measurements on the remaining six compounds indicates that their over-all accuracy is likewise of this same order.

    Notes: A first approximation to the multicomponent plate-efficiency problem has been carried out with a film model combined with equations for steady state diffusion in a ternary gas mixture. Numerical integration of the equations through a plate yields the ternary efficiencies as functions of the binary efficiency.The effects of diffusional interactions in a distillation column were studied by computing the efficiencies on each plate when a column is designed to separate a ternary mixture. In the example studied, the average column efficiency was 39% less than the binary efficiency.Some criteria are suggested for comparing other multicomponent systems to the one studied in order to estimate the uncertainty in the use of binary correlations for these systems.

    Notes: A new correlation is presented for predicting the pressure-volume temperature relations of nonpolar (and slightly polar) gases. The correlation modifies the law of corresponding states in which a third parameter, the slope of the pseudocritical isometric in dimensionless form, is introduced. This parameter is introduced in a simple manner by multiplying the reduced pressure and temperature of the gas by a factor which can be easily calculated or read from a graphs. This gives the corrected reduced pressure and temperature which can then be used with a generalized compressibility factor chart in place of the true values. The correlation is accurate for densities up to about 1.2 times the critical density.A detailed comparison of the method with data on twelve pure gases showed that by introducing this parameter into the law of corresponding states the average error was decreased from 1.598 to 0.320%. The parameter S can readily be determined from experimental PVT data, and only one isotherm is required. S is related to the vapor-pressure curve for a substance as characterized by the critical pressure and the ratio of the critical temperature to the normal boiling temperature, and a simple method is proposed for predicting S when no experimental data are available.A new set of generalized compressibility factor and fugacity to pressure ratio charts is presented for use with the proposed correlation. A method is also presented for determining the thermodynamics functions.

    Notes: Mixing rates in agitated vessels are predicted through measurement of the flow patterns which determine them. These measurements suggest the use of a model that assumes that nearly all the mixing occurs in a small “perfectly mixed” region near the impeller, with flow throughout the remainder of the tank serving primarily to bring the fluid into this region of the impeller.On the basis of this model, equations were developed for relating volumetric flow rates, hence the mixing rates, to the operating variables. While the theory could be checked directly only to Reynolds numbers of slightly over 600 (owing to limitations of the experimental technique employed in this part of the mixing-rate studies), the volumetric flow rates could be measured from Reynolds numbers of 36 to 1.7 × 104. The times required for completion of an acid-base neutralization (terminal mixing) were also measured from Reynolds numbers of 1.6 to 1.8 × 105.Flat-blade, dimensionally similar turbines with diameters of 2, 4, and 6 in. were used. Tank diameters ranged from 5.76 to 15.5 in. The baffle width equaled one tenth of the tank diameter in all runs. All the data were for Newtonian fluid systems, but the extension of this work to non-Newtonian materials is discussed briefly.

    Notes: In stirred beakers the interfacial area between xylene containing a scintillator and tritiated water was measured as a function of stirrer speed by a scintillation counting technique. Because of the 6 μ average range of the tritium betas the rate at which flashes are detected by a phototube is a function of the interfacial area. A calibration curve of count rate against known interfacial area for unstirred phases in containers of various diameters gave a numerical estimate of the interfacial area for ten configurations.

    Notes: Experimental data were obtained on the effect of bed length of packed spheres on axial diffusion coefficients with the frequency response technique used. Lengths of packed section of 6 to 174 cm. were used. The end effects were eliminated by using a novel experimental technique for analyses of the inlet and outlet streams. No effects of length on DL were found.When the end effects were artificially introduced by using void analytical sections at the two ends, then large effects of length on DL were found. These void sections were the cause of length effects found by other experimenters. The DL drops as the length of bed is increased. Above about 65 cm. length the DL remains constant with increase in length. The over-all results are in general agreement with the data of others.

    Notes: By use of the Benedict-Webb-Rubin (BWR) equation of state an attempt has been made to correlate experimental vapor-liquid equilibrium data on hydrogen-methane-propane mixtures in the temperature range from 0° to -250°F. and pressure range from 500 to 1,500 lb./sq. in. abs. Considerable improvement in hydrogen K values has been obtained by adjusting the coefficient ν in the BWR equation for hydrogen. In the final adjustment it was necessary to specify a new value of ν for hydrogen at each temperature. The root-mean-square deviation of calculated from observed K values for hydrogen is 6.6%As a further check the recommended BWR coefficients for hydrogen have been used to calculate the low-temperature hydrogen K values in mixtures with ethane and ethylene with good results.The predicted K values for propane at temperatures below -150°F. have not been altered and are still in error by as much as 2 orders of magnitude.

    Notes: Maximum stable droplet size in nonuniform dispersoids may be ignored or treated as a statistical-limiting parameter or as a physically significant quantity. In this paper the author shows that treatment as a physically significant quantity is always permissible and in most cases advantageous. It is found that maximum stable droplet size as well as a mean droplet size can be calculated in some cases from theory and in other cases from correlated experimental data; this is illustrated with examples involving sprays and emulsions.

    Notes: Motion pictures at 2,000 frames/sec. were used to measure the movements of individual solid particles and gas bubbles in a fluidized bed. Air was used to fluidize 0.028-in. glass spheres and 200-mesh alumina in a 3.75-in. glass column. Aggregates were very common, and each moved as a unit. Particles and aggregates near the wall showed pronounced alternations of fast and slow movements both upward and downward. Individual particles exhibited spin. Baffles increased the bed density and decreased the particle velocities. Small bubbles rose rapidly with little change in shape. Large cavities were slow and tended to collapse and reform elsewhere.

    Notes: Thermodynamic analysis of phase-equilibrium data is necessary for testing such data, for extension to new conditions, and for purposes of correlation and prediction of phase-equilibrium behavior. While such analysis is common for low-pressure systems, it is rare for high-pressure systems owing to difficulties encountered in the definition of standard states. For a gaseous solute in the liquid phase it is proposed that the standard state be taken as the hypothetical liquid at the temperature and total pressure of the solution. The properties of this standard state are specified by the temperature and total pressure and by the specific volume which the substance would have if it did not experience a phase change. This standard state is useful since it is not a function of the solution but only of the substance being considered. For a condensable component in the gas phase it is convenient for most purposes to define the standard state as the ideal gas at the temperature and total pressure of the solution, but to separate the effect of composition on the activity coefficient from that of pressure, it is proposed to define the standard state as the real hypothetical gas at the solution conditions. To illustrate these ideas, activity coefficients are computed for several high-pressure systems, and it is shown how these activity coefficients may be used in the correlation, testing, and extension of high-pressure phase-equilibrium data.

    Notes: From studies of annular packed beds wherein the heat flows purely radially, the authors obtained the coefficients of heat transfer on the inner tube surface, as well as the mean effective thermal conductivities of bed. The inner and outer diameters of the annular packed bed were 22 and 70 mm. respectively, and the packings shown in Table 1 were used. The wall film coefficients obtained with air flowing axially through the bed were correlated for NReM 〈 600 by means of Equation (14).The coefficients of heat transfer for cylindrical packed beds reported previously by other observers were correlated also by Equation (14), with 0.054 used for values of αω in the range NReM 〈 2,000.Consideration of Equation (14) in terms of a theoretical model of heat transfer showed that it was reasonable to apply it for the prediction of wall film coefficient, especially for low Reynolds numbers.

    Notes: A corresponding-states correlation for the liquid-state properties of higher molecular-weight substances is presented which contains as reducing parameters the readily measurable (and correlatable) energy vaporization and van der Waals volume instead of the often inaccessible critical constants. One additional parameter characterizing molecular flexibility is introduced.A single curve of the new reduced density ρ* vs. the new reduced temperature T* is shown to represent the atmospheric-pressure-density-temperature relations of paraffinic, naphthenic, and aromatic hydrocarbons with 10 or more carbon atoms per molecule to within ±1% between their melting and their atmospheric boiling points. The reduced surface tension is shown to be a unique function of ρ± for many compounds, thus permitting prediction of surface tension over wide ranges of temperature. The heat-capacity difference between liquid and vapor proved to be easily correlatable with ρ±. Finally the compression of numerous hydrocarbons proved to be well correlated in terms of T*, ρ±, and P*. Extensive group data for Vw and E° have been assembled in the appendix in order to enable others to use the proposed method without effort.

    Notes: Hydrocarbon vapor-liquid equilibria are expressed in terms of K values, which are functions of composition, as well as pressure and temperature. The composition effect in the liquid phase is calculated by the Hildebrand-Scatchard equation for regular solutions. The parameters in this equation, called solubility parameters, can be calculated simply from heat of vaporization for the heavier hydrocarbons, but an indirect method of calculation must be used for the lighter components. Solubility parameters for hydrogen, methane, ethane, and propane were computed from gas-solubility data in several hydrocarbon solvents at various temperatures and pressures. This computation also yielded simultaneously the fugacities of the hypothetical liquid-standard states.The results presented are not complete for practical applications, owing to the scarcity of suitable solubility data, especially at high temperatures and pressures. However solubility parameters appear to give the right liquid-phase corrections in the correlation and prediction of hydrocarbon phase equilibria. Calculated K values for light hydrocarbons in paraffinic, naphthenic, and aromatic absorption oils are compared with experimental results. The average deviation for the forty-two values tested is 13%.

The compressibility factors are reported as smoothed values at even pressures and also in the form of empirical smoothing expressions which fit the experimental values with an average absolute deviation of 0.1%. Various methods of predicting gas-mixture compressibility are tested, and activity coefficients calculated from the experimental data are reported.

    Notes: A new theory gives a simple method of calculating the terminal velocity of fluid particles moving in media of either infinite or restricted extent.Empirical and semiempirical formulas [Equations (27) and (30)] and a graph (Figure 6) over the interval 0 ≤ d/D ≤ 1.3 are shown to yield satisfactory results for gas or liquid particles moving in liquid media. In the case of liquid drops falling through gaseous media they give only a rough approximation.Graphs showing the variation of the drag coefficient (Figure 1) and the shape (Figure 2) of fluid particles with the Eötvös number are given. A semiempirical equation for the terminal velocity of solid spheres in restricted media has also been developed [Equation (24)].

    Notes: The approach presented for the prediction of critical temperatures and pressures for hydrocarbons from the van der Waals' constants a and b (1) has been extended to permit the estimation of these constants for other organic compounds. Analogously, contribution values for a number of functional groups have been established, and the majority were found to depend on the size of the organic molecule. Information presently available in the literature (4) has permitted the establishment of values for functional groups in organic compounds of the following types: alcohols, phenols, ethers, ketones, carboxylic acids and esters, amines, nitriles, and halides. These functional group contributions, in conjunction with the values previously developed for the hydrocarbons, now make possible the calculation of both van der Waals' constants from only structural considerations. Once these van der Waals' constants have been established, the critical temperature and pressure are readily calculated.With the approach developed in this investigation critical temperatures and pressures for eighty-one organic compounds have been calculated and when compared with literature values produced average absolute deviations of 1.36% for the critical temperature and 2.32% for the critical pressure.

    Notes: Longitudinal mixing properties in liquid-solid fluidized beds were investigated by means of a salt-solution tracer technique. The electrical conductance breakthrough curves were measured with very small electrical conductivity probes for a step-function input of salt-solution tracer. Longitudinal eddy diffusivities were determined for 1.3- and 3.0-mm. lead spheres and 3.2-mm. glass spheres in 2- and 4-in.-diameter beds at a distance of 5 bed diam. from the injector and for various radial positions.The longitudinal mixing properties are strongly affected by particle concentration; maximum mixing occurs at a fraction voids of 0.7. Longitudinal eddy diffusivity increases with particle density and with decreasing dp/D ratio. Velocity profiles markedly influence the eddy-diffusivity profiles.

    Notes: Experiments were carried out with cylindrical thermal-diffusion columns in which the separation chambers were sufficiently narrow so that curvature effects might be ignored. For both open and closed operation, results were obtained for the two binary systems benzene-carbon tetrachloride and n-heptane-benzene as well as the ternary mixture n-heptane-methylcyclo-hexane-toluene. For the binary systems, correlations are given in terms of dimensionless combinations which arise when the equations of conservation are placed in dimensionless form. The thermal-diffusion coefficients used in the correlations are literature values determined in steady-state-cell (no convection) measurements.

    Notes: A method of determining the absolute calibration of a gas-flow orifice without the use of gas holders or any comparative device is described. The method is based on the application of the momentum balance, as well as the energy balance, to the flow of the gas. The application requires the measurement of pressures on the face of the orifice in addition to the usual pressure-drop measurements along the axis of flow.Orifice coefficients determined by the force-momentum principle are shown to agree within an average deviation of 1.4% with those determined by other standard techniques. Also the application of the force-momentum principle demonstrates clearly why orifice coefficients are much less than unity.

    Notes: The present paper extends the previous investigations from this laboratory on ideal fluidized systems to a system which is somewhat nonideal. Mixtures of different but well-defined glass spheres are fluidized by water to ascertain whether the principles developed for a single particle size still hold. The analysis indicates that the ideal prediction method gives a reasonable representation of the batch-expansion curves for mixed sizes.

    Notes: A rigorous mathematical description, consisting of differential-difference equations, is presented for binary batch rectification in the plate type of column. Two approaches are taken to solving these equations for the condition of constant reflux ratio: an integration by numerical means employing an IBM 650 computer, and a hand calculation procedure that involves trial-and-error computation of batch-rectification curves, which is of interest primarily where high-speed computing equipment is not available.Enthalpy balances are used to avoid assumption of equal rate of overflow in the tower; weight units are used instead of mole units; means for accounting for holdup in the condenser-accumulator system are described. Criteria of convergence and stability of the numerical solution are presented. The validity of the results of the proposed calculation procedures is substantiated by the close agreement of experimental and calculated batch-rectification curves.

    Notes: The results of an investigation of heat transfer and reaction kinetics in a fixed-bed catalytic reactor of slab geometry are described. The particular reaction studied is the air oxidation of nitric oxide with silica gel. Conversions and catalyst-bed temperatures were observed in the experimental, nonisothermal slab reactor, but only a sample of these data are reported and analyzed here.A mathematical analysis of the processes occurring in a slab reactor has been developed which leads to a design method for such reactors that permits prediction of catalyst-bed temperatures and conversions from a knowledge of specific reaction rates and the physical properties of the system. The design method involves a step-by-step procedure but requires a small number of steps. To evaluate the accuracy of the design method and to illustrate its use, the specific reaction-rate data together with published thermal-conductivity data have been used with the method to predict the results of a run on the experimental nonisothermal reactor. Good agreement between calculated and observed temperatures and conversions was obtained.Specific reaction rates, derived from integral conversions in an experimental, isothermal reactor, are reported.

    Notes: Asymptotic expressions are presented in this paper for the mass transfer Nusselt number in both forced- and free-convection laminar-boundary-layer flows with large interfacial velocities directed toward the surface. The analysis is valid for arbitrary surface geometries and includes transfer in a variable properties fluid. It is shown, in addition, how these asymptotic formulas may be used in conjunction with the Nusselt number for zero interfacial velocities to estimate the rate of mass transfer for the intermediate regions.

    Notes: An investigation has been made of transient heat transfer and water removal on an unfelted cylinder dryer. This investigation has included the development of a theory for describing conduction of heat in the drying material and an experimental testing of the adequacy of the theory.The theory describes the heat transfer and evaporation of water in terms of a second-order partial-differential equation and appropriate boundary conditions. Numerical solutions obtained on a digital computer are presented.The experimental work, performed on a specially constructed laboratory dryer, included measurements of temperatures at internal points in a drying sheet and also measurements of water removed during drying.Good agreement was found between theory and experiment, and the usefulness of the theory is demonstrated in the analysis of water removal in some drying experiments.Although the work was primarily concerned with a description of the paper drying process, the methods should apply equally well to the drying of other materials on heated cylinders.

    Notes: Vapor-pressure data available in the literature for olefins, diolefins, and acetylenes have been used to establish the constants of the Frost-Kalkwarf equation (9). This equation requires the establishment of constants A, B, C, and D and defines accurately the vapor-pressure function ever the complete range included between the triple point and the critical point. Constant D has been shown to be equal to a/2.303R2. Both van der Waals' constants can be predicted from the molecular structure (33), thus enabling the calculation of the critical temperatures and pressures for these unsaturated hydrocarbons. Constant B has been found also to depend on the molecular structure of these hydrocarbons.The normal boiling point of an aliphatic hydrocarbon in conjuction with its critical point and the values B and D calculated from structural considerations permit the calculation of constants A and C. All four vapor pressure constants were calculated for twenty-seven monoolefins, nine diolefine, and five acetylenes for which reliable vapor-pressure data are presented in the literature. Comparisons between calculated values and values reported in the literature produced an average percentage deviation of 0.63 for the monoolefins, 2.65 for the diolefins, and 1.13 for the acetylenes. For the forty-one unsaturated aliphatic hydrocarbons considered in this investigation the average deviation was 1.14% for the randomly selected points of comparison.

    Notes: The interfacial areas formed in various immiscible liquid pairs by an orifice mixer were measured by a photoelectric method, which had been calibrated photographically. In addition to the variation of the liquid pair, total flow rate, volume fraction of the dispersed phase, and the orifice diameter, the pipe diameter of the mixing orifice was also varied. It was found that the formation of interfacial area could be correlated as a function of the change in kinetic energy across the mixing orifice, the energy required to overcome the viscous forces within the dispersed phase, and the volume fraction of the dispersed phase.

    Notes: Measurements were made of the flow structures in two types of spiral flow fields. The first was a vortex tube in which air entered one end of an 8-in. pipe through an involute entry and left at the opposite end. The second was a conventional cyclone separator in which the same entry was used.The experimental results show that the mean and turbulent flow structures are not sensitive to changes in the flow rate, but they are greatly affected by the geometry of the system. In the vortex tube the angular velocity is nearly constant at radial distances less than one-half of the radius of the pipe. The flow patterns in the vortex tube and in the cyclone are not symmetrical with the pipe axis. The asymmetry can be explained by postulating a dynamic center line with helical shape. The longitudinal intensity of turbulence increases sharply near the center of the vortex tube. This is caused primarily by the abrupt decrease in mean velocity near the center. The radial intensity also increases near the center, but near the wall it decreases rapidly with distance from the center. The longitudinal intensity of turbulence in the cyclone is highest near the center and near the wall. The high intensity near the wall is caused both by the decrease in mean velocity and the increase in root-mean-square turbulent velocity.

    Notes: By means of a procedure similar to that used for the inert gases (19) and methane (20) a reduced thermal conductivity correlation was developed for ethylene from experimental data available in the literature (2, 3, 4, 9, 13). The resulting correlation permits the prediction of thermal conductivities for gaseous and liquid ethylene in the temperature range TR = 0.4 to TR = 6.0 and for pressures up to PR = 50. For pressures below PR = 0.5 this correlation was found to apply to gaseous aliphatic hydrocarbons and their derivatives but not to cyclic compounds. For these aliphatic hydrocarbons and their derivatives the relation between thermal conductivity at atmospheric pressure and temperature is k*/k+c = 0.364 T1.786R.Experimental thermal conductivities of ethylene in the liquid state and dense-phase region were compared with values predicted by the reduced-state correlation. The average deviation for thirty-six experimental points was 1.8%. Gaseous-state data at atmospheric pressure of alkanes, alkenes, alkynes, alcohols, ethers, halogenated derivatives, esters, aldehydes, ketones, amines, nitriles, and other aliphatic compounds were also compared with values predicted by this correlation. For 414 experimental points the average deviation was 1.63%.

    Notes: By means of a moveable sensing probe previously described2 local shell-side heat transfer coefficients and friction losses were measured on a model tubular heat exchanger containing orifice baffles. The heat exchanger shell was 6-in. nominal I.D. and 45 in. in length and contained four tubes in triangular arrangement passing through orifice baffles. Baffle hole diameters of 1-/16, 1-2/16, 1-3/16, and 1-5/16 in. and baffle spacings of 4.0 and 9.0 in. were studied. Data were taken at several air flow rates for each of the four baffle hole diameters.The average heat transfer coefficient for the region between two central baffles was correlated with an empirical equation based on only two baffle spacings.An increase in the baffle-to-tube clearance caused a decrease in heat transfer. An increase in the baffle spacing also resulted in a decrease in heat transfer. Four flow zones in the baffle space are postulated from the analysis of Nusselt number distribution along the tube. The heat transfer characteristics in each of the four flow zones were analyzed in terms of the mechanism of the fluid flow.The pressure-drop data were correlated in terms of an annular orifice coefficient of discharge and an orifice-pressure-drop function. As a result of this study a method was developed by which one can predict the average of the local coefficients at the baffle position from the knowledge of pressure drop across a single baffle.

    Notes: A study was made of the evaporation from single drops containing solids. By means of a specially designed sensitive balance, drops were suspended over a hot-air stream and their drying behavior was observed. Weight changes were measured during evaporation. Experimental data are presented on the time of appearance of the first solid phase and the formation of a solid crust for a wide range of drying conditions and materials. A theory is advanced for predicting the formation of a solid phase in drying a droplet containing a dissolved solid. This theory shows reasonable agreement with the experimental results. A tentative proposal for the application of the results to spray-dryer performance is suggested.

    Notes: A study was made of the effects the surface tension of aqueous solutions of surface-active agents had on the bubble-formation characteristics of these solutions. Bubbles were formed by two processes: by passing air through a horizontal orifice submerged in the solution and by nucleate boiling at an electrically heated surface. The experimental measurements taken with the air-bubble system were used to determine the nature of the surface-tension effect on air-bubble formation. This knowledge was then applied to the interpretation of boiling measurements made with the same solutions. The boiling coefficients of the Tergitol-water solution were found to vary inversely with dynamic surface tension. Boiling coefficients for Aerosol-water solutions, however, varied in a manner which could not be related to surface-tension effects.

    Notes: The constant-volume heat capacities of gaseous perfluorocyclobutane and propylene have been measured over a considerable range of temperatures and densities with a new type of adiabatic calorimeter. This calorimeter differs from previous constant-volume gas calorimeters in having very thin walls and being equipped with an internal motor stirrer to provide temperature uniformity. The experimental results have been compared with the predictions of the Benedict-Webb-Rubin and Martin-Hou equations, by use of published values of the zero-pressure-constant-volume heat capacity. The over-all agreement is satisfactory, with a maximum difference between the experimental and calculated heat capacities of 6.7%; however the comparison reveals several interesting systematic differences between the experimental and calculated values of the derivatives of the constant-volume heat capacity with respect to temperature and density.

    Notes: A correlation has been developed to predict the thermal conductivity of packed beds for various conditions of pressure, temperature, and particle size. The correlation takes into account the reduction in thermal conductivity of the gas phase at lower pressures when the mean free path of the gas molecules is of the same order as the distance between particles which are effective in transferring heat. Radiation becomes significant for large particles and high temperatures. A new relationship for the radiation contribution to the thermal conductivity of packed beds has been developed.

    Notes: Techniques for solving the equilibrium flash problem are reviewed and a new technique especially adapted for use on automatic digital computers is developed. Instead of a single equation with multiple roots being solved by an iterative process, as is usually done, the problem is rephrased as a differential equation, and a numerical integration is made. The isothermal and isobaric flash problems can be handled with essentially the same equations. The method is particularly advantageous when a complete flash curve is required and the equations can be used when a linear model of the equilibrium flash process is required.

    Notes: Detonation velocities were measured in mixtures of hydrogen and oxygen containing 25 to 75 mole % hydrogen at initial temperatures from 160° to 580°K. and initial pressures from 1/2 to 2 atm. The measurements were made in a number of tubes of different diameter to permit extrapolation to a tube of infinite diameter. Theoretical detonation characteristics were computed for the same range of conditions. The measured and computed velocities are in good agreement except in rich mixtures and at subatmospheric pressures. Schlieren photographs reveal that the detonation wave front is very thin for a stoichiometric mixture but degenerates to a complicated zone of interacting shock waves and turbulent combustion as the percentage of hydrogen is reduced. The detonation velocity is found to depend only slightly on initial temperature and pressure. The computed pressures behind the detonation and reflected waves are roughly proportional to initial pressure and to the reciprocal of the initial temperature.

    Notes: Irregular particles bounce with randomly distributed angles of reflection. There is a certain probability that a particle striking at low angle will bounce at a high angle and be carried far out into the main fluid flow. Bounce phenomena were investigated with respect to bounce of a model particle, limitations on dust collection (back mixing), and energy loss during the flow of suspensions.

    Notes: The flow patterns obtained when viscous fluids are agitated inside baffled cylindrical tanks have been studied in both Newtonian and non-Newtonian systems. The experimental technique consisted of observing the motions of small tracer particles in highly illuminated, narrow beams of light.The results may be broken down into two major categories. The first was a qualitative comparison between the flow patterns obtained in non-Newtonian and Newtonian fluids of the same general viscosity levels. This part of the study included observation of changes in the flow fields as one moves from laminar into turbulent conditions for both fluid systems.The second portion of the paper deals with quantitative determinations of local flow velocities, shear rates, and power-dissipation rates in various parts of the vessel. The following conclusions may be drawn from these measurements.1. Local fluid shear rates were found to be directly proportional to impeller speed, in both Newtonian and non-Newtonian systems. As would be expected, the shear rates decreased more rapidly with increasing distances from the impeller in pseudoplastic non-Newtonian fluids than in Newtonian systems.2. The rates of local power dissipation decreased rapidly with distance from the impeller.3. The fluid velocities in the horizontal plane of the impeller varied almost linearly with rotational speed in the Newtonian systems, in accordance with prior observations. On the other hand, movement in pseudoplastic systems increased exponentially with impeller speed. This effect, like the dampening of shear rates, is caused by the cumulative effects of local velocity and viscosity changes in these systems. (Increases in velocity decrease the fluid viscosity, which in turn causes further increases in velocity, etc.)This work serves to define pertinent problems which are of importance in determining mixing rates, on a microscopic scale. Efforts may now perhaps be turned more profitably than before toward macroscopic fluid-mixing studies.

    Notes: General equations for the temperature dependence of the parameters of the Hudleston equation are given which were deduced from a study of n-alkane compression data. Empirical expressions for the molecular-weight dependence of the constants of these equations are likewise given which are applicable only to n-alkanes. By use of these relations in the Hudleston equation the compressions of the family of liquid n-alkanes over ranges of T, P, and m were calculated on an IBM-650 computer. The over-all standard percentage error (SPE) of the computer calculations for n-alkanes of 7 to 20 carbons up to temperatures not exceeding their normal boiling points was 0.10%. The over-all SPE for n-alkanes of 7 to 40 carbons up to temperatures substantially above their normal boiling points (but not exceeding 300°C.) was 0.21%.

    Notes: The rate of heat and mass transfer in the nozzle zone of water sprays produced by internal-mixing pneumatic nozzles and hollow-cone pressure nozzles was determined for both concurrent and crosscurrent drying air-flow patterns. The Nusselt numbers for the evaporating drops were correlated by means of the equation proposed by Ranz and Marshall for stationary drops in a moving air flow. Methods of measuring the physical properties of the water-air system were developed, and special attention was devoted to the determination of drop velocities and air humidity.

    Notes: The usual tedious method of construction of enthalpy-concentration charts for solutions of solids requires data seldom available. A new, simple method is therefore presented that utilizes more readily available data, that is vapor pressures of the solutions. These plot as straight lines on a logarithmic-reference substance plot. Differences from unity of the slopes of these lines represent heats of solution, and when this difference function is integrated between concentration limits the integral heat of solution is obtained. The enthalpy chart is then readily constructed by use of the specific heats of liquid and solid.Ammonium nitrate is the solid used in this example, and water is the liquid because of the industrial importance of aqueous solutions. Vapor pressures were carefully determined experimentally, and the enthalpy chart was developed from the straight lines of the logarithmic plot and available heat data. Constants for the vapor-pressure curves for ammonium nitrate solutions and equations for enthalpies of solid ammonium nitrate are given for the temperature range 0° to 170°C.

    Notes: Solution rates of 1/2-, 3/4-, and 1-in. cast benzoic acid spheres were measured under natural-and forced-convection conditions. Upward-flowing streams of water and aqueous propylene glycol, in laminar and turbulent flow, were used to contact single spheres in either a 1.50- or 4.00-in.- diameter column. Sphere Reynolds numbers ranged from 10 to 16,920; Schmidt numbers from 987 to 69,680; sphere- to column-diameter ratios, ds/dc, from 0.123 to 0.497; and Grashof numbers from 5,130 to 125,200.The Sherwood number was found independent of the laminar-turbulent transition for pipe flow and the sphere- to column-diameter ratio when the Reynolds number is based on the average fluid velocity and sphere diameter.A correlation of the data based on the additivity of the natural and forced convection processes is proposed, and statistical analyses of the new experimental data result in equations which correlate other heat and mass transfer data for single spheres immersed in bounded and free-jet streams of gases and liquids for NRe, S from 1 to 30,000 and NSe from 0.6 to 3,000, within an average deviation of about 20%.

    Notes: The two vertical halves of the wall of a 4.3-in. I.D. cylinder were maintained at different uniform temperatures. The rate of circulation of air inside the cylinder and the local rate of heat transfer between the wall and air were derived from measurements of the velocity and temperature fields in the air for wall-temperature differences from 3.5° to 367°F. The overall rate of circulation was found to increase quite rapidly and then to decrease slowly as the wall-temperature difference was increased. The over-all Nusselt number based on the wall-temperature difference was found to have an approximately constant value of 7.0.Numerical solution of the partial differential equations describing the conservation of mass, momentum, and energy for this system was investigated with an IBM-650 magnetic drum computer. Instabilities in the computational procedure and limitations of this computer prevented solution of the general problem. However specification of the velocity field obtained from experiment yielded a numerical solution for the temperature field in good agreement with the experimental measurements.

    Notes: Apparatus is described for experimentally determining diffusion coefficients in dense-gas systems to pressures of 15,000 lb./sq. in. abs. Tests were made with the hydrogen-nitrogen and methane-ethane systems at 104°, 139°, and 171°F. to 10,000 lb./sq. in. abs. and with the nitrogen-methane and nitrogen-ethane systems at 104°F. to 2,500 lb./sq. in. abs. In all cases it was found that diffusion coefficients predicted on the basis of the Lennard-Jones model with Thorne's dense-gas correction diverged below the experimental data in the high-density region. Coefficients predicted from the Slattery-Bird reduced-state correlation showed better agreement with the experimental data. The temperature dependence of the results is better described by the exponential form for liquids than by the form of the dense-gas theory.
