Equilibrium properties of high-density fluids

Abstract

A recipe is given extending the theory of Weeks, Chandler, and Anderson to the calculation of high‐density equilibrium properties of a fluid near its freezing point. Thermodynamic properties for a Lennard‐Jones system and a system whose particles obey an inverse 12th‐power repulsive potential are computed using this recipe. The calculation shows that the present formulation predicts physically reasonable values for the hard‐sphere diameter over the entire dense fluid region and gives thermodynamic data which agree satisfactorily with the available Monte Carlo data.
