    Notes: Abstract In order to provide the newest and most reliable numerical data of thermophysical properties of fluids to the scientific and technical community as quickly as possible, the present data-base system was designed and constructed. This data base is concerned with 12 kinds of thermophysical properties at 7 defined physical states for about 400 pure fluids and their binary mixtures. The present system is constructed by means of a data-base management system, INQ, on our computer ACOS series System-2020 produced by Nippon Electric Co. Ltd. The data base is usable as (i) the conversational processing by TSS, (ii) the tabulation of property data in batch processing, and (iii) one of the subroutine libraries in the computation of a user's program. For users' convenience, 10 kinds of application programs have been prepared for the multipurpose retrievals, and anyone can use this data base liberally without any special knowledge on the structure or languages of this system. Furthermore, the function of graphic display of property data has been added recently.

    Notes: Abstract Viscosities of six higher 1-alkanols (1-hexanol, 1-octanol, 1-decanol, 1-dodecanol, 1-tetradecanol, and 1-hexadecanol) have been determined at temperatures from 298 to 348 K and pressures up to 200 MPa. The viscosity measurements were performed using a falling-body viscometer with an uncertainty of ±5%. Simple equations are presented to express the experimental viscosities as a function of temperature and pressure within the experimental uncertainty. The relationship between the viscosity and the density of these alkanols is discussed in terms of the significant structure theory extended to high pressures.

    Notes: Abstract Molar volumes, thermal expansion coefficients, and isothermal compressibilities of six higher 1-alkanols (1-hexanol, 1-octanol, 1-decanol, 1-dodecanol, 1-tetradecanol, and 1-hexadecanol) have been determined at temperatures from 298 to 348 K and pressures up to 40 MPa. The density measurements were performed using a vibrating densitometer with an uncertainty of ±0.06%. The relationship between the properties and the structures of these alkanols is discussed in terms of the carbon-chain lengths.

    A new correlation for the viscosity of gaseous fluorocarbon refrigerants (1986)
    Springer
    International journal of thermophysics 7 (1986), S. 1023-1031 
    Details
    ISSN: 1572-9567
    Keywords: dimensional analysis ; fluorocarbon ; gas mixture ; generalized correlation ; principle of corresponding states ; refrigerant ; viscosity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract A new generalized correlation is presented for the low-pressure gaseous viscosity of fluorocarbon refrigerants. The following empirical equation is obtained based on the most reliable experimental data for 16 fluorocarbons: $$\eta \xi = \left( {0.5124T_r - 0.0517} \right)^{0.82} Z_c ^{ - 0.81}$$ where η is the viscosity in μPa·s and ξ is the viscosity parameter defined using the critical temperature T c in K, the critical pressure P c in MPa, and the molar mass M in g·mol−1 as follows: $$\xi = T_c ^{1/6} M^{ - 1/2} P_c ^{ - 2/3}$$ The applicable ranges are 0.6〈T r〈1.8 and 0.253〈Z c〈0.282. The availability of the correlating equation for both pure fluorocarbons and their mixtures has been investigated based on the experimental data of these authors and those in the literature. It is found that the present correlation is useful for the prediction of the viscosity of pure fluorocarbons and their binary mixtures at atmospheric pressure with mean deviations less than 1.6%.

    Notes: Abstract New experimental data on the density and viscosity of linear, unbranched perfluoropolyethers are presented at temperatures from 273 to 333 K and pressures up to 180 MPa. The measurements were carried out by a high-pressure burrette apparatus and a falling-cylinder viscometer. The uncertainties of the measurements are estimated to be less than 0.09% for the specific volume and 2.5% for the viscosity. The P-V data at each temperature are correlated satisfactorily by the Tait equation. The viscosity data are also analyzed and correlated with pressure or molar volume by several empirical and theoretical equations.

    Notes: Abstract The specific volumes of C1-C4 alcohols and binary mixtures of water with methanol, ethanol, 1-propanol, 2-propanol, and 2-methyl-2-propanol are presented as functions of temperature, pressure, and composition. The measurements were carried out using a modified Adams piezometer and a high-pressure burette method in a temperature range from 283.15 to 348.15 K at pressures up to 350 MPa. The uncertainties in the specific volume obtained are estimated to be less than 0.09%. The specific volumes of the pure alcohols and their mixtures with water are found to decrease monotonously with increasing pressure. The numerical P-V relations at each temperature and composition are correlated satisfactorily as a function of pressure by the Tait equation. Definite inflections appear on the isobars of isothermal compressibility or partial molar volume versus composition of alcohol + water mixtures.

    Solid-liquid phase equilibria of benzene + cyclohexane system under high pressures (1987)

    Topics: Physics
    Notes: Abstract Solid-liquid phase equilibria of the benzene + cyclohexane system have been investigated experimentally at temperatures from 278 to 323 K and pressures up to 500 MPa using a newly designed optical vessel. The uncertainties of the measurements of temperature, pressure, and composition are within ±0.1 K, ±0.5 MPa, and ±0.001 mole fraction, respectively. The solid-liquid equilibrium pressure at a constant composition increases almost linearly with increasin temperature. The eutectic point shifts to a higher temperature and to a benzenerich composition with increasing pressure. This trend is found to agree with the direction predicted by the van Laar equation. The solid-liquid coexistence curves can be expressed by the Wilson equation with a mean deviation of 0.007 and a maximum deviation of 0.029 in mole fraction.

    Topics: Physics
    Notes: Abstract New experimental viscosity data are presented for aqueous solutions of methanol, ethanol, 1-propanol, 2-propanol, and 2-methyl-2-propanol (t-butyl alcohol) in the temperature range from 283 to 348 K and pressures up to 120 MPa. The viscosity measurements were performed using a falling-cylinder viscometer on a relative basis with an uncertainty of less than 2%. The viscosity of pure alcohols and aqueous solutions is found to increase almost linearly with increasing pressure, whereas that of water decreases slightly with pressure at temperatures below 298 K. As for the composition dependence of the viscosity, a distinct maximum appears near 0.3–0.4 mole fraction of alcohol on all isobars at each temperature. The viscosity maximum shifts gradually to a higher alcohol concentration with increasing temperature and pressure. The isobars of aqueous 2-propanol and 2-methyl-2-propanol solutions have another shallow minimum near 0.9 mole fraction of alcohol below 323 K. The experimental results were analized empirically by a Tait-type equation and a free-volume theory. It was found that the isothermal viscosity data were satisfactorily correlated by these equations as functions of pressure and composition or of density and composition.

    Electric resistivity anomaly and martensitic phase transformation in Cu-Al-Zn alloy (1986)

    Notes: Abstract The quenched Cu-16.5Al-14.9Zn alloy has been examined by electric resistivity and X-ray diffraction measurements. It is confirmed that electric resistivity anomaly (ERA), observed so far in the quenched Au-Cd and Au-Cu-Zn alloys, appears also in the present alloy quenched from the Heusler type β 1-phase region followed by heating. ERA is considered to be due to annihilation of quenched-in vacancies with activation energy of about 0.33eV. The appearance of ERA modulates considerably schema of the martensitic phase transformation, especially the transformation temperature. In this paper, the reason why ERA does not appear in the case quenched from disordered β-phase region, and the quenching effect on premartensitic and other behaviours are discussed in detail.
