    An improved representation forn-alkane liquid densities (1994)
    Springer
    International journal of thermophysics 15 (1994), S. 155-164 
    Details
    ISSN: 1572-9567
    Keywords: n-alkanes ; density ; high pressure ; Tait equation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract New experimental density data have been used to improve a recently published correlation ofn-alkane densities, based on the Tait equation. The new correlation covers then-alkanes from methane ton-hexadecane in an extended pressure range of up to 500 MPa in some cases. The overall average deviation of the experimental measurements of the density from those calculated by the correlation is ±0.10%. A simple extension to n-alkane mixtures gives a satisfactory prediction of the density compared with experimental data.

    Correlation and prediction of dense fluid transport coefficients. VII. Refrigerants (1995)
    Springer
    International journal of thermophysics 16 (1995), S. 761-772 
    Details
    ISSN: 1572-9567
    Keywords: density ; high pressure ; refrigerants ; Tail equation ; thermal conductivity ; viscosity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract A recently developed scheme, based on considerations of hard-sphere theory, is used for the simultaneous correlation of the coefficients of viscosity and thermal conductivity for the refrigerants R11, R12, R22, R32. R124, R125, R134a, R141b, and R152a in excellent agreement with experiment, over extended temperature and pressure ranges. Values for the roughness factors and correlations for the characteristic volume are presented. The overall average absolute deviations of the experimental viscosity and thermal conductivity measurements from those calculated by the correlation are 2.1 and 2.3%, respectively, over a temperature range from 200 to about 10 K below the critical temperature and a pressure range from saturation to about 40 MPa. Since the proposed scheme is based on recent and accurate density values, a Tail-type equation was also employed to correlate successfully the density of the refrigerants. The overall average absolute deviation of the experimental density measurements from those calculated by the correlation is ±0.08%.

    The Tait equation: 100 years on (1988)
    Springer
    International journal of thermophysics 9 (1988), S. 941-951 
    Details
    ISSN: 1572-9567
    Keywords: density ; high pressure ; Tait equation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The “Tait equation,” which is now widely used to fit liquid density data over wide pressure ranges, is a modification of the original equation of Tait, published 100 years ago, to fit his results on the compressibility of fresh water and seawater at different pressures. The range of applicability of these different equations is discussed and it is concluded that their simplicity and accuracy in reproducing high pressure density data for dense gases, liquids, solids, and liquid mixtures will ensure their continued use.

    Correlation and prediction of dense fluid transport coefficients. VI.n-alcohols (1994)
    Springer
    International journal of thermophysics 15 (1994), S. 189-201 
    Details
    ISSN: 1572-9567
    Keywords: n-alcohols ; density ; high pressure ; self-diffusion ; Tait equation ; thermal conductivity ; viscosity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract A previously described method, based on considerations of hard-sphere theory, is used for the simultaneous correlation of the coefficients of viscosity, self-diffusion, and thermal conductivity for then-alcohols, from methanol ton-decanol, in excellent agreement with experiment, over extended temperature and pressure ranges. Generalized correlations are given for the roughness factors and the characteristic volume. The overall average absolute deviations of the experimental viscosity, self-diffusion, and thermal conductivity measurements from those calculated by the correlation are 2.4, 2.6, and 2.0%, respectively. Since the proposed scheme is based on accurate density values, a Tait-type equation was also employed to correlate successfully the density of then-alcohols. The overall average absolute deviation of the experimental density measurements from those calculated by the correlation is ±0.05%.

    Transport properties of nonelectrolyte liquid mixtures—VI. Viscosimetric study of binary mixtures of hexafluorobenzene with aromatic hydrocarbons (1985)
    Springer
    International journal of thermophysics 6 (1985), S. 21-41 
    Details
    ISSN: 1572-9567
    Keywords: aromatic hydrocarbons ; density ; excess free energy of activation ; Grunberg and Nissan equation ; hexafluorobenzene ; viscosity coefficient
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Viscosity coefficients for binary mixtures of hexafluorobenzene with benzene, toluene, para-xylene, and mesitylene have been measured along the saturation line at temperatures from 15 to 120°C using specially designed capillary viscometers. Densities were measured using a pyknometer and volume-change apparatus. Deviations of the viscosities from a rectilinear dependence on mole fraction are consistent with enhanced interactions between unlike species, which increase with increasing number of methyl groups on the aromatic hydrocarbon and decrease with increasing temperature. The application of the Grunberg and Nissan equation, the Hildebrand equation, and energy of activation theories to these results is examined.

    Densities of n-alkanes and their mixtures at elevated pressures (1987)
    Springer
    International journal of thermophysics 8 (1987), S. 541-555 
    Details
    ISSN: 1572-9567
    Keywords: alkanes ; density ; high pressure ; liquid mixtures ; Tait equation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Accurate density data for n-alkanes over a wide range of temperature and pressure have been used to test existing correlation and prediction methods. It is found that the most successful representation at temperatures up to 0.66 times the critical temperature and pressures up to 150 MPa is given by the Tait equation in the form (ρ−ρ0)/ρ=C log [(B + P)/(B + P 0)], where subscript 0 refers to 0.101 MPa, with C equal to 0.2000, and [B+(C n −6)], where C n is the number of carbon atoms in the alkane chain, is a smooth function of reduced temperature. A simple extension of this method to mixtures gives an excellent prediction of densities at pressures up to 150 MPa over the same reduced temperature range.
