    Notes: Abstract  The effects of organic residues and inorganic fertilizers on P availability and maize yield were compared in a Nitisol of western Kenya. Leaf biomass of Calliandra calothyrsus, Senna spectabilis, Croton megalocarpus, Lantana camara, Sesbania sesban, and Tithonia diversifolia were incorporated into the soil at 5 Mg ha–1 for six consecutive seasons in 3 years and responses compared with those following the application of 120 kg N ha–1, 0 kg P ha–1 (0P); 120 kg N ha–1, 10 kg P ha–1; and 120 kg N ha–1 25 kg P ha–1 as urea and triple superphosphate (TSP); K was supplied in all treatments. Addition of Tithonia, Lantana and Croton increased soil resin-extractable P over that of fertilizer-amended soil throughout the first crop, but the amounts in the former treatments became similar to those for soils amended with inorganic fertilizers for subsequent crops. Addition of Sesbania, Calliandra and Senna had a similar effect on resin P as inorganic fertilizers. Total maize yields after six seasons were tripled by the application of Tithonia compared to 0P, and were higher than those of the Calliandra, Senna, Sesbania and Lantana treatments, and similar only to that of the Croton treatment. P recovered in the above-ground biomass and resin P, immediately after the implementation of the treatments, was higher in the Senna, Sesbania, Croton, Lantana and Tithonia (35–77%) treatments than in the inorganic fertilizer treatments (21–27%). The P content of organic residues, and the soluble C:total P ratio, were the main residue parameters predicting soil P availability and maize yield. All organic residues used in this study can replace inorganic fertilizers for the enhancement of P availability and maize production, while an additional benefit could be obtained from the use of Croton, Lantana and Tithonia.

    Notes: Abstract  A pot experiment was conducted with soil from a long-term (74-year) fertilization field experiment to compare the effects of organic and mineral fertilizers on mycorrhiza formation in clover, and mycorrhiza-mediated plant P uptake. Five treatments were selected from the field experiment representing different forms and levels of P. Mycorrhizal effects on plant growth and P uptake were estimated by comparing plants grown in untreated soil containing indigenous arbuscular mycorrhizal (AM) fungi, with plants grown in pasteurized soil. Short-term versus residual effects of fertilizer/manure were also measured by comparing treatments with or without fertilizers added at the start of the pot experiment. Mycorrhiza formation was greatest in soil that had received no P for 74 years, followed by soil having received 30 or 60 Mg ha–1 farmyard manure (FYM), and soil having received 25 or 44 kg P ha–1 in NPK fertilizers. Plant growth and P uptake were severely reduced in the absence of AM fungi for all mineral fertilizer treatments. In contrast, plants growing in soil that had received FYM grew equally well or better when non-mycorrhizal. Recent additions of NK fertilizer and FYM had no effect on mycorrhiza formation, while additions of NPK led to reduced colonization. It thus seems that moderate quantities of FYM have less adverse effects on AM than equivalent amounts of nutrients in NPK fertilizers, a phenomenon that is most likely due to a temporal difference in P availability and its gradual release that balance plant demand.

    Notes: Abstract  The effect of prolonged (9 week) nutrient enrichment on the growth and photosynthetic rates of the zooxanthellate coral Stylophora pistillata was investigated. The main questions were: (1) what is the exposure time needed to induce measurable change in growth rate? (2) which are the concentrations of nitrogen and phosphorus required to cause changes in these rates? (3) what is the recovery potential of the corals after the nutrient stress? For this purpose, three tanks (N, P, NP) were enriched with ammonium (N), phosphorus (P) or both nutrients (NP), respectively. A fourth tank (C) served as a control. The growth of 40 nubbins (10 in each tank) was monitored during four periods: period 1 (nutrient-poor conditions), period 2 (10 μm NH4 and/or 2 μm PO4 enrichment), period 3 (20 μm NH4 and/or 2 μm PO4) and period 4 (nutrient-poor conditions). Period 4 was performed to study the recovery potential of corals after a nutrient stress. During period 1, growth rates remained constant in all tanks. In the P tank, growth rates declined during the two enrichment periods, with a total decrease of 60% by the end of period 3. In the N tank, growth rates remained nearly constant during period 2 but decreased in period 3 (60% decrease). In the NP tank, 50% and 25% decreases were observed during periods 2 and 3. At the end of the recovery period, a regain in growth rate was observed in the N and NP tanks (35 and 30% increase, respectively, compared with the rates measured at the end of period 3) and growth rates returned to 60% of the initial rates. By contrast, in the P tank, there was no regain in growth and a further decrease of 5% was observed. Rates of photosynthesis were often higher during the enriched than the nutrient-poor period (up to 150% increase). Corals with the highest percent increases in maximal gross photosynthetic rate (P g max ) had the smallest decreases in growth rate due to nutrient enrichment. In conclusion, high ammonium (20 μm) and relatively low phosphorus concentrations (2 μm) are required to induce a significant decrease in coral growth rate. The largest reduction was observed with both ammonium and phosphorus enrichment. The decrease in growth rate was rapid following nutrient enrichment, since a 10% decrease or more could be observed after the first week of treatment.

    Notes: Summary Arbuscular mycorrhizal (AM) fungi significantly improve plant growth in soils with low phosphorus availability and cause many changes in root morphology, similar to those produced by increased P nutrition, mainly depending on root apex size and activity. The aim of this work was to discriminate between the morphogenetic role of AM fungi and P in leek (Allium porrum L.) by feeding mycorrhizal and nonmycorrhizal plants with two nutrient solutions containing 3.2 or 96 μM P and examining specific parameters related to adventitious root apices (apex size, mitotic cycle, and RNA synthesis). The results showed that AM fungi blocked meristem activity as indicated by the higher percentages of inactive apices and metaphases in the apical meristem of mycorrhizal plants, whereas the high P supply lengthened the mitotic cycle without blocking the apices, resulting in steady, slow root growth. The possible involvement of abscisic acid in the regulation of root apex activity is discussed.

    Notes: Abstract To evaluate the effects of bone meal powder (BEC) on calcium and phosphorus metabolism, a calcium absorption test was conducted using a preparation of calcium carbonate (CAC) as the control drug. A total of 12 healthy volunteers, consisting of 6 younger (aged 20–29 years, 3 men and 3 women) and 6 older (aged 60–69 years, 3 men and 3 women) persons, were subjected to a double-blinded crossover study. Serum calcium (s-Ca) level significantly increased to 105.3% ± 1.9% (P 〈 0.01 vs the basal value; mean ± SD) from the basal value in the BEC group and to 104.4% ± 2.7% (P 〈 0.01) in the CAC group at 3 h post load. Urinary excretions of calcium (u-Ca/glomerular filtration rate, u-Ca/GF) after BEC and CAC load rose to 226.6% ± 154.5% (P 〈 0.05) and 211.1% ± 148.0% (P 〈 0.05), respectively. Serum phosphorus (s-P) levels after BEC load increased to 110.0% ± 15.1% (P 〈 0.05), whereas that after CAC load showed no significant change (99.3% ± 7.9%). On the other hand, urinary excretion of phosphorus (u-P/GF) after CAC load decreased to 60.0% ± 32.4% (P 〈 0.01) and that in the BEC group showed no significant change (92.5% ± 49.5%). The increase in s-Ca led to decrease in serum intact parathyroid hormone (i-PTH) level [77.3% ± 33.4% (P 〈 0.05) for BEC and 69.5% ± 20.3% (P 〈 0.01) for CAC] although s-P was increased by the BEC load. The responses to BEC and CAC administration were compared in the younger and the older groups. The responses in the younger and the older group showed fundamentally the same trends and to the same extent. However, the changes in serum ionized calcium (i-Ca) and i-PTH levels at 1.5 h post load were significantly smaller in the older group than in the younger group (P 〈 0.01; P 〈 0.05). The increment in s-P level after BEC load in the older group was larger than that in the younger group. In conclusion, BEC can modulate not only calcium but also phosphorus metabolism in both younger and older subjects. Further investigations are required to evaluate the effects of BEC on bone density and safety for renal function in long-term observations.

    Notes: Starting from R′R2P (R′ = 8-dimethylamino-1-naphthyl) containing a donor dimethylamino group, the new phosphonium salts [R′R2P(CH2Ph)]+Br- [R = Me (9) or Ph (10)] and [R′R2P(p-CH2C6H4CH2)PR2R′]2+[2Br]2- [R = Ph (12)] have been prepared. An interaction between the N and P atoms is evident from the X-ray crystal structure of 10 the N-P distance being less than the sum of the van der Waals radii of the 2 atoms. The geometry of 10 is that of a monocapped tetrahedron whereas the X-ray crystal structure determination shows essentially regular tetrahedral geometry for the analogous compound without the donor amino group, [(1-Np)Ph2P(CH2Ph)]+Br- (11). Treatment of 1,5-bis(dimethylamino)-2,6-dilithionaphthalene with chlorodiphenylphosphane gave 1,5-bis(dimethylamino)-2,6-bis(diphenylphosphanyl)naphthalene (8) which in the presence of methyl iodide afforded the diphosphonium salt [1,5-bis(dimethylamino)-2,6-bis(diphenylmethylphosphonium)naphthalene]2+[2I]2- (13). Similarly, treatment of 8 with 1 equivalent of benzyl bromide gave the monophosphonium salt [1,5-bis(dimethylamino)-2diphenylbenzylphosphonium-6-diphenylphosphanyl-naphthalene]+[Br]- (14) whereas in the presence of 2 equivalents of the same reagent [1,5-bis(dimethylamino)-2,6-bis(diphenylbenzylphosphonium)naphthalene]2+[2 Br]2- (15) was obtained. The ionomer poly([(1,5-bis{dimethylamino}2,6-bis{diphenylphosphonium}naphthalene)-(P,P-p-xylylene)]2+[2 Br]2-) (16), soluble in liquid SO2, was prepared by treatment of 8 with α,α′-dibromo-p-xylene.

    Notes: Ab initio quantum chemical calculations have been used to explore the P3H3 potential energy surface focussing on the ring-chain rearrangements of the three-membered ring in (PH)3 (1), the parent triphosphirane. Relative energies between stationary points were estimated using the QCISD(T)/6-311G(d,p) method based on MP2/6-31G(d,p) geometries and corrected for zero-point contributions. Ring strain, proton affinities, ionization and excitation energies and heats of formation have been evaluated using larger basis sets, e.g. 6-311++G(3df,2p). The cyclic trans-triphosphirane (1a) is the most stable P3H3 isomer and lies about 40 kJ/mol below the open-chain phosphanyldi-phosphene (H2P-P=PH). The decrease of ring strain in three-membered rings when CH2 is replaced by PH is confirmed. Triphosphirane 1a is a virtually strain-free ring and even gains some stabilization relative to three separate P-P single bonds. The reduced ring strain also helps diminish the phosphorus inversion barrier to 224 kJ/mol compared to the monocyclic isomers of (CH2)(PH)2 and (CH2)2(PH). Compound 1a follows a pure ring-opening or a 1,2-hydrogen shift rather than a combined motion pathway, in fundamental contrast with corresponding processes of diphosphirane and phosphirane. This is due to the existence of an open-chain P3H3 phosphorane intermediate stabilized by allylic conjugation. The pericyclic ring-opening of 1a is the most favored process but the energy barrier in the gas phase is about 180 kJ/mol high. Electron density is largely delocalized within the three-membered P3 ring not only in the C3v-symmetric 1b (all-cis) but also in 1a (Cs). The proton affinity of 1a is similar to that of PH3. The proton affinities decrease with n in cyclo-(CH3)3 -n(PH)n and their values were obtained: PA(1a) = 777 ±10, PA(diphosphirane) = 799 ±10 and PA(phosphirane) = 802 ±10 kJ/mol. Heats of formation are evaluated as follows (ΔH°f0 at 0 K in kJ/mol): 1a, 70 ±10; cyclo-(PH)2(PH2)+ (protonated 1a), 821 ±10; diphosphirane, 85 ±10; cyclo-(CH2)(PH)(PH2)+ (protonated diphosphirane), 814 ±10; phosphirane, 86 ±10; and protonated phosphirane, 812 ±10 kJ/mol. All P rings remain cyclic following ionization to the radical cations. Adiabatic ionization energies (IEa) are estimated as: 1a and diphosphirane, 9.3 ±0.3 eV and phosphirane 9.5 ±0.3 eV. The first UV absorption band shifts toward the longer wavelength region on going from phosphirane to 1a. The GIAO/B3LYP computed magnetic shieldings for 1a and related molecules reveal a clear relationship between the narrow bond angles in the rings and their unusually strong magnetic shielding. The similarity of the predicted 31P-NMR signals in 1a and its heteroanalog diphosphirane, (CH2)(PH)2, can be rationalized in terms of a compensation of the carbon-substituent effect (downfield shift) and the bond-bending effect imposed by the ring (upfield shift).

    Notes: The first 1,2-azaphosphindoles 14a,b, 15a,b were obtained in a straightforward manner upon heating diphenylzirconocene in the presence of a cyanophosphane, which afforded azazirconacyclopentenes 11a,b which can be reacted with various dichlorophosphanes. The use of the tetrachlorodiphosphane Cl2P(CH2)2PCl2 instead of a dichlorophosphane allowed the preparation of the bis(1,2-azaphosphindoles) 19, 19′. The monosulfur adduct of the azaphosphindole 14a, i.e. 16a, was characterized by X-ray structure analysis. Alkylation of 14a or 16a with methyltrifluoromethane sulfonate occurred selectively on the intracyclic phosphorus atom or on the sulfur atom, giving the salts 20 or 21, respectively.

    Notes: Thioesters of the phosphorous acid containing cymantrenyl and ferrocenyl substituents at sulfur were obtained for the first time from the reaction of organometallic disulfides with white phosphorus. According to an X-ray diffraction study tricymantrenyl trithiophosphite adopts an unusual asymmetric cis, gauche, trans conformation along the P-S bonds with respect to the phosphorus lone electron pair. Triferrocenyl trithiophosphate possesses a classical propeller-like structure in the solid state which is different from its oxygen analogue.

    Notes: Constant pressure diffusion rates of hydrogen through Vycor porous glass were measured in nitrogen and neon systems. The experimental diffusivities are less than those predicted by the random pore model indicating that this model may not be satisfactory for a low porosity material such as Vycor. Interpreted in terms of an assembly of parallel pores the data suggest a tortuosity factor of approximately 2.4.Rate data for the ortho-para hydrogen reaction were also measured at -196°C. and 1 atm. The catalyst 2% nickel/Vycor was found to have pore properties (area, mean pore size, pore volume) similar to that of plain Vycor. Predicted effectiveness factors using the experimental diffusion data were in good agreement with values determined experimentally. The latter were evaluated from rate measurements on both pellet and particles (58 μ mean diameter).

    Optimization by Pontryagin's maximum principle on the analog computer (1964)

    Notes: A computational method has been developed for obtaining the solution to a class of optimization problems by the combined use of the maximum principle and a maximum (or minimum) seeking technique on the analogue computer. Various maximum seeking techniques can be used for this method. However if the random search technique is used, this computational method has the advantage of being able to investigate a large number of operating (or controlling) variables.The calculation procedure is essentially a trial-and-error procedure which is alternately integration and maximum seeking operations. The variables over which the system is to be optimized are approximated by a finite number of straight line segments n. Thus the maximum (or minimum) of the Hamiltonian function which is obtained by the maximum principle need only be obtained at n + 1 points along the optimization path (or trajectory).To illustrate the use of the method the optimum operating variable profiles (or gradients) in a tubular chemical reactor were computed.The present method, in addition to making it easier to investigate systems with a moderate number of state variables, can be used to solve problems with almost any kind of constraints and performance index encountered in ordinary optimum design problems. It offers some possibilities for on-line optimizing control of a process. A special purpose analogue computer could be built for this use.

    Notes: The linearized equations of diffusion in a multicomponent system with flow and chemical reaction are shown to reduce to a set of equivalent binary diffusion equations.The concentrations and fluxes in a multicomponent system are described by linear combinations of appropriate solutions to the binary diffusion equation for steady and unsteady diffusion and convective mass transfer, laminar or turbulent.The rate of transfer of each component in a nonreacting n component system is a linear combination of the n-1 independent driving forces with proportionality constants which depend upon the multicomponent diffusion coefficients and appropriate binary mass transfer coefficients, while the concentration profile of each component is a linear combination of appropriate binary concentration profiles with proportionality constants which depend upon the multicomponent diffusion coefficients and the characteristic displacement from equilibrium of each component.The linearized theory is exact for small changes in concentration but needs further testing when the concentration changes and fluxes are large.

    Notes: The solutions of amines and water are in several respects among the most interesting that have been studied. They give some of the most perfect examples of lower consolute temperatures with fast breaking, almost flat solubility curves near the critical solution point. Their heat and entropy of solution are very high, and with few other solutions do the thermodynamic properties show greater sensitivity to molecular structure.The activity coefficients for these solutions are inordinately difficult to fit with equations such as the Margules, Redlich-Kister, etc., requiring as many as six constants. It has been found however that some of the properties can be correlated in terms of structural parameters which are measures of the steric and inductive contribution of the substituent groups. A very good correlation of the heat of solution at infinite dilution of amines in water is given. An equation of the Margules type employing orthogonal polynomials is given for which the constants are similarly correlated. Five six-carbon atom amines at 10°C. are included in the latter correlations, and the activity coefficients of all of these are represented in terms of two structural parameters.

    Effects of reduced gravity on nucleate boiling bubble dynamics in saturated water (1964)

    Notes: A study was made of nucleate boiling bubble dynamics in saturated distilled water for various reduced gravity fields. The nucleation occurred on a very smooth horizontal nickel surface at low heat fluxes. Since because of the smooth surface finish only a few nucleation sites were active, it was possible to photograph individual bubbles that were not interfered with by adjacent bubble columns. Data were taken at seven different gravity fields in the range from 1.4 to 100% of earth gravity by placing the apparatus on a counterwieghted falling platform. Measurements were made of bubble departure diameters and frequencies, growth rates, contact angles, base circle diameters, and rise velocities. Comparisons were made to determine whether the measured gravity dependence of these quantities was in agreement with that predicted by correlations in the literature.

    Turbulent disruption of flocs in small particle size suspensions (1964)

    Notes: In the absence of turbulent fluctuations the main effect of a velocity gradient on the floc properties is a rearrangement of particles within the floc producing a more dense floc structure. When the suspension is sufficiently dilute that floc-floc collisions are negligible, the limits on the floc diameter are (1 + α)5/3 〈 (Df/Dp) ≤ (1 + α)2, where α is the ratio of the volume of fluid immobilized in the floc structure to volume of solids in the floc structure as determined from hindred-settling measurements. These results set an upper limit on the floc size.Under turbulent flow conditions the principle mechanism leading to floc rupture is pressure differences on opposite sides of the floc which cause bulgy deformation and rupture. The breakup of the floc is resisted by the yield stress τy and is promoted by an increase in the energy dissipation per unit mass of fluid ∊. Because the energy dissipation per unit mass is at a maximum near the pipe wall, the floc size is at a minimum in this same region.By application of the concepts of local isotropy, the floc size is found to be proportional to (τy9/∊5)1/2once the turbulent intensity is sufficient to overcome the yield stress. In the wall region the floc diameter is proportional to (du/dr)3 (τy9/∊8)1/2.

    Notes: The purpose of this study was to develop the use of semibatch operation of a recirculation reactor in kinetic studies. Ethylene hydrogenation over a supported copper catalyst was studied experimentally. In semibatch operation one of the reactants is fed at the rate necessary to hold the total pressure in the reactor constant. In ethvlene hydrogenation the reaction rate is directly equal to the feed rate, and the kinetics can be studied at constant partial pressure of either of the reactants. Since ethane is inert, this technique permitted the study of reaction rate as a function of one variable at a time.Although ethylene hydrogenation has been studied extensively, there is not general agreement regarding the kinetics over a copper catalyst. The results are themselves of interest because they indicate the reasons for the apparently conflicting data in the literature.

    Notes: To test the importance of visco-elastic properties of non-Newtonian fluids in an oscillatory system of low frequency the dynamic characteristics of a series of non-Newtonian fluids were studied in oscillating manometers. The manometer fluid behavior was simulated on a digital computer by numerically integrating the axial component of the equation of motion. In the simulation cone and plate steady state rheological data were represented mathematically with the Sisko rheological model. Good agreement between simulation and experimental data was obtained. This agreement implies that steady state rheological models can be utilized in the description of unsteady state non-Newtonian systems where the characteristic period of the system is many times greater than the relaxation and retardation times of the fluid. When this characteristic period approaches these times, then rheological models which incorporate viscoelastic terms explicitly probably should be used.

    A numerical method for the solution of the energy equation for steady turbulent heat transfer (1964)

    Notes: A method is presented for solving the basic energy expression for the temperature distribution for turbulent heat transfer in a circular conduit with a digital computer. The method assumes a knowledge of the velocity distribution, the eddy conductivity term as a function of the radial position, and a constant wall temperature. For illustrative purposes only a dimensionless expression is derived from Reichardt's relationship which gives the eddy conductivity term as a function of radial position with Reynolds and Prandtl numbers as parameters.Incorporated in the computer program is Richardson's three-point extrapolation formula which permits the determination of a more accurate eigenvalue from three previously computed values which were obtained by using three different values of the reduced radial increment. Agreement with the Crank-Nicholson method is quite good, although the method with eigenvalues is considered to be superior. Eigenvalues determined from the analytical solution of the energy expression for the laminar flow case and those computed by the numerical method are in excellent agreement. This is indicative of the accuracy and reliability of the proposed numerical method.

    Notes: Outline below is a method for simplification of the solution of diffusion problems involving irreversible first-order reactions. It permits writing the concentration profiles for reactive systems in terms of those for nonreactive systems of the same geometry and similar boundary conditions. The method is valid where fluid flow patterns and concentration boundary conditions are time independent and where the assumptions of constant density and mass diffusivity are acceptable. The useful results of this development are summarized in Equations (31) through (33) and represent a generalization of an earlier development by P. V. Danckwerts (1).

    Kinetics of hydrogen reduction of ferrous oxide in a batch fluidized bed: Effects of mass velocity and pressure (1964)

    Notes: The kinetics of reduction of ferrous oxide with hydrogen were studied in a 1½-in. diameter isothermal batch fluidized reactor. The effects of mass velocity and pressure on the reduction path were investigated over the ranges 5.3 to 19.2 moles/sq.ft.hr. and 1.3 to 5.4 atm. at 1,000° and 1,300°F. The results are correlated by means of instantaneous oxygen balances on the assumptions that there are no oxygen concentration gradients in the solid phase, that the distribution of residence times for the gas flow is represented closely by assuming complete mixing, and that the reduction rate is controlled at the oxide-metal interface. The rate of reduction increased with increasing pressure and mass velocity. An excellent correlation was obtained for the program at 1,000°F. At 1,300°F. sintering and grain growth of the product layer complicated the reduction process, and a correlation was not obtained. Application of the results to the design of commercial fluidized-reduction processes is discussed qualitatively.

    Transport characteristics of suspensions: Part IX. Representation of periodic phenomena on a flow regime diagram for dilute suspension transport (1964)

    Notes: Four different flow regimes may be identified during transport of dilute suspensions of solid particles through horizontal pipes by liquids in turbulent flow as the velocity is varied. The regimes may be characterized by the distribution of solids in the channel. In two of the regimes the bulk of the material is immediately adjacent to the bottom of the channel and is clumped up either into transverse waves (dunes or islands) with a reproducible periodicity or into longitudinal waves (long stria). The definition of the other two regimes is somewhat more arbitrary but may qualitatively be described as heterogeneous or homogeneous flow. Extensive studies of the conditions under which transverse and longitudinal waves occurred, when combined with results of previous studies, showed that all four of these flow regimes may be conveniently represented on a single diagram in which the terminal-settling velocity divided by the friction velocity and the Reynolds number on particle diameter and friction velocity are the coordinates. Because the particle Reynolds number based on the terminal-settling velocity can be uniquely defined as an additional parametre on such a diagram the particular flow behavior for any given combination of system and particle characteristics can be readily determined.

    Notes: Significant changes in heat and momentum transfer rates can be caused by finite interfacial velocities and external field forces. This study considers the nonlinear problem of combined free and forced convection in vertical and horizontal two-dimensional conduits with finite transverse velocity.Similarity transformations for the temperature function have been found which reduce the energy, momentum, continuity, and state equations for these configurations to nonlinear systems of two coupled ordianary differential euqations. These equations are solved by approximate methods to give Nusselt numbers and friction factors as well as velocity and temperature profiles.Stream to wall temperature differences increase with suction and decrease with injection. The effects of interfacial velocity on temperature profiles and heat transfer increase dramatically with Prandtl number. Because blowing and suction strongly affect temperature profiles they substantially modify natural convection effects in vertical flows. Suction creates steeper transverse temperature gradients and accentuates buoyancy effects in vertical flows. Conversely injection flattens temperature profiles and thus decreases the influence of buoyancy on the velocity field.

    Formation of air bubbles at orifices submerged beneath liquids (1964)

    Notes: The results of two investigations are reported. Air bubbles were formed at orifices submerged beneath each of fourteen liquids. The surface tension of the liquids varied from 17.8 to 72.4 dynes/cm., and the viscosities ranged from 0.436 to 713 centipoise. In the first investigation, air bubbles were formed at orifices at various angles of inclihation. Orifice diameters ranging from 0.159 to 0.396 cm. were employed. The air-flow rate was varied from 0.1 to 100 cc. (at standard conditions)/sec. The results were obtained with two different apparatuses by three independent investigators.In the second investigation, the effect of the velocity of a liquid flowing past a horizontal, submerged orifice on the formation of air bubbles was determined. Liquid velocities ranging from 0.34 to 2.5 cm/sec., which spanned the region of laminar flow, were employed. Orifice diameters ranged from 0.15875 to 0.3175 cm., air-flow rates from 0.5 to 100 cc/sec. (at standard conditions).It was found that the bubble formation observed in each of these investigations could be correlated with the physical variables of the system by the application of Newton's second law of motion to the bubble at the instant just prior to its release from the orifice.

    Notes: The calculus of variations, dynamic programing, and Pontryagin's maximum principle all are methods for optimzing serial decision processes, the kind associated with multistage operations having no recycle or bypass. Addition of recycle to a serial process makes it cyclic, and branching structures can be built up by connecting serial ones. The concept of cut state makes possible the decomposition of cyclic and branched systems into serial ones solvable by serial procedures. Under favorable circumstances cut states can be directed to their optimum values by efficient optimum seeking methods, which is not possible for ordinary state variables. These method are worthwhile only for loops having at least three stages, and the treatment of converging branches is more complicated than for diverging ones. Visualization of the various system structures is aided by functional diagrams. Definitions and nomenclature are developed for continued research on optimization of macrosystems by serial techniques.

    Phase-volume relationship at the point of phase inversion in liquid dispersions (1964)

    Notes: The point of inversion of a water-in-oil type of dispersion to an oil-in-water type is investigated for several water-oil systems by studying the volume ratios of the phases in relation to their physical properties. The point of inversion for each system of an immiscible organic liquid and water and organic liquid mixture and water is obtained by varying the phase-volume ratios and determining the type of dispersion after complete mixing. The effects of temprature, interfacial tension, and density are found to have no correlation generally applicable to the systems studied. A volume-viscosity relationship is found to exist within limits. This correlation is that the phase-volume ratio at the point of inversion is equal to the square root of the ratio of teh viscosities of the respective phases at the interface. The theoretical aspects of this relationship are studied along with its limitations.

    Notes: Unusual heat transfer phenomena have been observed between solid surfaces and fluids near their thermodynamic critical point. To understand better these phenomena temperature and velocity profiles and local heat transfer coefficients were measured for turbulent flow of carbon dioxide in a tube at 1,075 lb/sq. in. abs. (pc = 1,071). The results indicate a severe flattening of the radial temperature profiles, a maximum in the velocity profile between the wall and the tube axis, and a maximum in h' when the bulk fluid temperature passes through the transposed critical temperature.The results can be explained qualitatively by considering the variation with temperature of thermal conductivity near the tube wall and specific heat in the turbulent core.

    Notes: Turbulent mixing of a dye solution injected at the center of a pipe was studied by means of a new light probe developed for the measurement of concentration fluctuations were made both along the axial distance and across the pipe. The concentration fluctuations persisted longer at the center-line region than anywhere else; this suggested the use of the decay of intensity at the center as an upper limit. Approximately 99% of the initial intensity decayed within 7.5 ft. (30 L/d). The concentration spectra along the axial distance indicated that the eddies initially undergo a scalar energy cascade. Because of the huge difference in the kinematic viscosity and molecular diffusivities the concentration spectra extend much farther toward high wave numbers than the velocity spectrum. Apparently a state of imbalance resulted between the supply of small eddies and their dissipation; this was marked by the appearance of a small hump in the spectra. The phenomenological approximations of Corrsin and of Beek and Miller could be used for the practical problem of predicting the decay of the intensity of the concentration fluctuations or mixing in the pipe geometry studied.

    Notes: The adiabatic, evaporating, two-phase flow of steam and water in horizontal pipe including the critical flow was successfully described by a system of nonlinear differential equations which include different phase velocities, fluid acceleration, wall shear forces, interface shear forces, and mass and energy transfer between the phases. The solution of the differential equations by the method of Runge-Kutta was facilitated with a high-speed digital computer. Experimental data were obtained which included void fraction measurement by X-ray attenuation and showed that the theoretical equations described the complex flow phenomena to ± 10% when radial temperature gradients were small. Design charts based on the numerical solution of the theoretical equations are presented for rapid evaluation of the flow variables for the system steam-water including critical flow for inlet pressures from 30 to 150 lb./sq.in.abs., mass flow rates per unit area from 300 to 1,000 lb./sq. ft. sec., and L/D ratios from 25 to 1,000. The critical flow is defined as the maximum flow rate for a given pressure at the point of initial vaporization and L/D ratio.
