On-the-Fly Second Virial Coefficients
The Journal of Physical Chemistry B, 2021A simple but approximate algorithm is described for computing second virial coefficients based on equilibrated molecular configurations that may be generated during any Monte Carlo or molecular dynamics simulation. The algorithm uses simple quadrature based on sampling every binary pair in the configuration and moving their center-center distances from

Fluid Phase Equilibria, 2007
Abstract Second and third virial coefficients ( B and C ) for the T range from about the critical temperature to the Boyle temperature are presented for argon, carbon dioxide, ethane, hydrogen, methane, nitrogen, oxygen, and propane. That these virial coefficients are more reliable than those previously available is demonstrated by the ability of

Second Virial Coefficient of Polar Gases
The Physics of Fluids, 1962The theoretical expressions for the second virial coefficient, B(T), are derived for the (18–6-3) Stockmayer potential Φ(r)=4ε[(σr)18−(σr)6]−μ2r3g(θ1,θ2,φ),where g(θ1, θ2, φ) = 2 cos θ1 cos θ2 − sin θ1 sin θ2 cos φ, and also according to the (28–7-3) potential.

Virial coefficients of Lennard-Jones mixtures
The Journal of Chemical Physics, 2009We report results of calculations of the second through sixth virial coefficients for four prototype Lennard-Jones (LJ) mixtures that have been the subject of previous studies in the literature. Values are reported for temperatures ranging from T=0.6 to T=10.0, where here the temperature is given units of the LJ energy parameter of one of the ...

CHAPTER 6. Virial Coefficients
2014The virial equation of state of a gas is a series expansion of the pressure in powers of inverse molar volume, the mth coefficient of which is given by a set of exact cluster integrals involving m molecules. For mixtures, the composition dependence of the virial coefficients can be expressed exactly in terms of interaction virial coefficients and the ...

Fifth virial coefficient of a hard-sphere mixture
Molecular Physics, 1996New calculations of the ® fth virial coe cient are presented for binary hard sphere mixtures. These improve on, and in some cases correct, previous results. A polynomial ® t is used to extend the results to all diameter ratios, with an accuracy better than 1.05%.

Second virial coefficient for directed manifolds
Physical Review A, 1991The second virial coefficient for a D-dimensional polymerized manifold with only mutual repulsive interaction for the same internal D coordinate has been calculated using the perturbative renormalization-group method. This can be carried out to all orders of the perturbative expansion for this model.
