‘An old chestnut: can the virial expansion describe the vapour-liquid phase transition?’

by Prof Andrew Masters FRSC,
School of Chemical Engineering & Analytical Science, University of Manchester.

Abstract:

The virial expansion seeks to represent a system property, such as the pressure, as a series expansion in the density. This approach was introduced by Kamerlingh Onnes in 1901 and later put on a firm, theoretical foundation by Mayer and Mayer in 1940. For a classical fluid, where the particles interact via pairwise additive forces, the nth virial coefficient can be written as a sum of integrals involving the pair potential and the temperature. These expressions become extremely complicated for large values of n, but recent technical advances have allowed the numerical evaluation of these coefficients to high order. For example 16 coefficients have recently been calculated for…
