Review of data for Velocity of Sound in pure liquid metals and metalloids
International Materials Reviews, 2020Co-Authors: S. BlairsAbstract:AbstractA review of the experimentally determined values of the Velocity of Sound c in molten pure liquid metals and metalloids has been carried out. Based on the available data for each element, recommended Velocity–temperature relationships have been suggested. A range of thermophysical properties has been derived from these values. Theoretical models for the Velocity of Sound and its temperature dependence have also been considered. Sound velocities have also been estimated via the inter-relationship of Velocity to other thermophysical properties.

Use of the Velocity of Sound in predicting the PVT relations
Fluid Phase Equilibria, 1993Co-Authors: Mohammad R. Riazi, G. Ali MansooriAbstract: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, 2007Co-Authors: Miyuki Hayashi, Hirokage Yamada, Naozumi Nabeshima, Kazuhiro NagataAbstract: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, 2020Co-Authors: A. Van Itterbeek, W. Van Dael, W. GrevendonkAbstract: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.
