    Phase behavior of the system He-N2 at high pressures (1989)
    Springer
    International journal of thermophysics 10 (1989), S. 15-25 
    Details
    ISSN: 1572-9567
    Keywords: binary mixtures ; diamond anvil cell ; helium ; high pressure ; nitrogen ; phase equilibria
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Recent investigation at our institute revealed that the solid-fluid-fluid three-phase line of the system helium-nitrogen shows two quadruple points in the pressure range up to 10 GPa. Since each quadruple point is connected with four three-phase lines, the phase diagram is very complicated. We have detected the phase transitions representing solid-solid-fluid equilibria. Moreover, two lines of constant composition have been determined as a function of temperature and pressure. These results are discussed together with the implications for the phase diagram of both He-N2 and pure nitrogen.

    ISSN: 1572-9567
    Keywords: high pressure ; propane ; thermal conductivity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract This paper presents thermal conductivity measurements of propane over the temperature range of 192–320 K, at pressures to 70 MPa, and densities to 15 mol · L−1, using a transient line-source instrument. The precision and reproducibility of the instrument are within ±0.5%. The measurements are estimated to be accurate to ±1.5%. A correlation of the present data, together with other available data in the range 110–580 K up to 70 MPa, including the anomalous critical region, is presented. This correlation of the over 800 data points is estimated to be accurate within ±7.5%.

    Thermal conductivity of B2O3 glass under pressure (1985)
    Springer
    International journal of thermophysics 6 (1985), S. 267-273 
    Details
    ISSN: 1572-9567
    Keywords: high pressure ; thermal conductivity ; vitreous boron trioxide
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The thermal conductivity, λ, of vitreous boron trioxide was measured, using a hot-wire procedure, from 170 to 570 K and under pressures of up to 1.7 GPa. The thermal conductivity at room temperature and zero pressure was found to be 0.52 W · m−1 · K−1. The values of the logarithmic pressure derivative, g = d(ln λ)/d(ln ρ), where ρ is the density, were found to be 1.1 for uncompacted glass and 0.7 for glass compacted to 1.2 GPa. The variation of λ with temperature at constant density was approximately linear, with a positive slope of 1.38×10−3W·m−1·K−2.

    Notes: Abstract Experimentally determined p,V,T data are reported for toluene, trichloromethane, dichloromethane, acetonitrile, aniline, and n-dodecane at 278, 288, 298, 313, and 323 K, except for dichloromethane, for which the highest temperature was 298 K. At each temperature, measurements were done at pressures up to about 280 MPa or (for aniline and n-dodecane) at a lower pressure slightly below the freezing pressure at the temperature of measurement. Values of the isobaric expansivity isothermal compressibility and (for toluene, trichloromethane, dichloromethane, and acetonitrile) internal pressure, derived from the p,V,T data, are presented.

    Vapor-liquid equilibrium and volumetric properties calculations for solutions in the supercritical carbon dioxide (1986)
    Springer
    International journal of thermophysics 7 (1986), S. 635-646 
    Details
    ISSN: 1572-9567
    Keywords: carbon dioxide ; critical phenomena ; equations of state ; high pressure ; phase equilibria ; solutions
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The calculations of gas solubilities in supercritical solvents require equations of state remaining accurate in the critical range, which are difficult to obtain with classical models. In this work, the Helmholtz energy of a mixture is considered as the sum of the Helmholtz energies of pure components taken at a constant packing fraction and of a residual term which may have the form of a RedlichKister, Van Laar, NRTL, UNIQUAC, or UNIFAC function. Thus it is possible to assign to a given component an equation of state whose form is different from that of the others. This model has been applied to binary systems containing supercritical carbon dioxide. The results are improved with respect to those obtained with the classical model for vapor-liquid equilibria and for volumetric properties.

    Temperature and pressure effects on the thermal conductivity of TlCl and TlBr (1987)
    Springer
    International journal of thermophysics 8 (1987), S. 607-620 
    Details
    ISSN: 1572-9567
    Keywords: high pressure ; hot-wire method ; thallium bromide (TlBr) ; thallium chloride (TlCl) ; thermal conductivity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The hot-wire method was used to measure the thermal conductivity of both TlCl and TlBr. The measurements were performed in the temperature range 120–300 K and at pressures up to 2.3 GPa. An analysis of the thermal conductivity data showed that the Leibfried-Schlömann formula is a better description for TlBr than for TlCl. For both TlBr and TlCl the effect of optic phonons on thermal conductivity cannot be ignored.

    Solid-liquid phase equilibria of (α-methylnaphthalene + β-methylnaphthalene) and (chlorobenzene + bromobenzene) systems under high Pressures (1987)
    Springer
    International journal of thermophysics 8 (1987), S. 671-680 
    Details
    ISSN: 1572-9567
    Keywords: bromobenzene ; chlorobenzene ; high pressure ; α-methylnaphthalene ; β-methylnaphthalene ; solid-liquid phase equilibrium ; solid solution
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Solid-liquid phase equilibria of the (α-methylnaphthalene + β-methylnaphthalene) and the (chlorobenzene + bromobenzene) systems have been investigated at temperatures from 278 to 343 K and pressures up to 500 MPa using a high-pressure optical vessel. The uncertainties of the measurements of temperature, pressure, and composition were within ±0.1 K, ±0.5 MPa, and ±0.001 mole fraction, respectively. In both systems, the freezing and melting pressures at a constant composition increase almost linearly with increasing temperatures. In the former system, where the two components can form a solid solution with one another to a limit extent, the eutectic point shifts to a higher temperature and to a α-methylnaphthalene-rich composition with increasing pressures. In the latter system, where the two components are completely soluble in each other in the solid phase, the freezing points of all mixtures lie between those of the pure components at each pressure. It is found that the coexistence curves obtained can be expressed by a quadratic equation in pressure.

    Thermal conductivity and thermal diffusivity of xylene isomers in the temperature range 308–360 K at pressures up to 0.38 GPa (1988)

    ISSN: 1572-9567
    Keywords: heat capacity ; high pressure ; m-xylene ; o-xylene ; p-xylene ; thermal conductivity ; thermal diffusivity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract New, absolute measurements of the thermal conductivity of the three xylene isomers within the temperature range 308–360 K for pressures up to 0.38 GPa are reported. In addition, for two of the isomers, m-xylene and p-xylene, it has been possible to measure the thermal diffusivity simultaneously within the same range of conditions. The accuracy of the thermal conductivity data reported is one of ±0.3%, whereas for the thermal diffusivity the estimated accuracy is ±6%. It is found that the density dependence of the thermal conductivity for all of the xylenes can be well represented by one equation based on a rigid-sphere model in the same way that has proved successful for normal alkanes. The thermal diffusivity data have been employed to derive heat capacities for the xylenes over a range of pressures.

    Notes: Abstract New measurements of the thermal conductivity of steam have been performed in the temperature range 250–510°C and in the pressure range from 1 up to 95 MPa. Most of the measurements were taken at temperatures greater than the critical temperature, where the enhancement of the thermal conductivity is observed. The experimental values are compared to the IAPS formulation for the thermal conductivity of water.
