  • Use of the Velocity of Sound in predicting the PVT relations
    Fluid Phase Equilibria, 1993
    Co-Authors: Mohammad R. Riazi, G. Ali Mansoori
    Abstract:

    Thermodynamic properties of fluids are generally calculated from the PVT relations through equations of state. The majority of existing equations of state require the critical properties or intermolecular potential energy parameters as their input data. In many cases, such properties are neither available nor they can be accurately estimated. One accessible and accurately measurable property of substances is the Velocity of Sound. In this report a method is introduced through which one can predict the PVT behavior of fluids using the Velocity of Sound data. A general mathematical relationship,

  • Temperature Dependence of the Velocity of Sound in Liquid Metals of Group XIV
    International Journal of Thermophysics, 2007
    Co-Authors: Miyuki Hayashi, Hirokage Yamada, Naozumi Nabeshima, Kazuhiro Nagata
    Abstract:

    The temperature dependences of the Velocity of Sound in liquid Pb, Sn, Ge, and Si have been measured by means of the pulse transmission technique over temperature ranges of 610–1078 K, 608–1463 K, 1215–1443 K, and 1723–1888 K, respectively. In both liquid Pb and Sn, the velocities of Sound decrease linearly with increasing temperature, which is the same temperature dependence as shown in many other liquid metals. On the other hand, the velocities of Sound in liquid Ge and Si exhibit anomalous temperature dependences. In Ge, the Velocity of Sound has a distinct maximum around 1280 K and decreases linearly at higher temperatures. In Si, the Velocity of Sound increases monotonically with increasing temperature in the temperature range investigated. It is considered that these results predict that the coordination numbers of liquid Ge and Si increase with increasing temperature.

  • Measurements on the Velocity of Sound in argon under high pressure
    Physica D: Nonlinear Phenomena, 2020
    Co-Authors: A. Van Itterbeek, W. Van Dael, W. Grevendonk
    Abstract:

    Synopsis Michels, A., Levelt, J. H. and Wolkers, G. J.1) calculated the variation of the Velocity of Sound in argon gas as a function'of pressure and temperature from their direct experimental data on the equation of state of argon. We carried out direct measurements on the Velocity of Sound and found a good agreement with the calculated values. Further we measured the change of the Velocity of Sound as a function of pressure in liquid argon at the boiling point of liquid oxygen. A linear variation was found.
