A Tensor Virial-Equation for Stellar Dynamics [PDF]
Monthly Notices of the Royal Astronomical Society, 1968 A tensor virial-equation is derived for a system consisting of equal mass-points, appropriately for stellar dynamics, by starting with the Liouville equation governing an ensemble of such systems in the six N-dimensional phase ...

New closed virial equation of state for hard-sphere fluids. [PDF]
Journal of Physical Chemistry B, 2016 A new closed virial equation of state of hard-sphere fluids is proposed which reproduces the calculated or estimated values of the first 16 virial coefficients and at the same time gives very good accuracy when compared with computer simulation data for ...

Equation of state for hard-sphere fluids offering accurate virial coefficients. [PDF]
Physical Chemistry, Chemical Physics - PCCP, 2016 The asymptotic expansion method is extended by using currently available accurate values for the first ten virial coefficients for hard sphere fluids. It is then used to yield an equation of state for hard sphere fluids, which accurately represents the ...

Study on anisotropic effect correction term of Virial–Peng–Long equation of state
AIP Advances, 2022 In order to correct the calculation deviation of the VPL (Virial–Peng–Long) equation of state (EOS) of gaseous detonation products, based on the L-J (Lennard-Jones) 6-12 spherical molecular potential, the change in the pressure–volume–temperature (PVT ...
