Computer "experiments" on classical fluids. I. Thermodynamical properties of Lennard-Jones molecules

Abstract

The equation of motion of a system of 864 particles interacting through a Lennard-Jones potential has been integrated for various values of the temperature and density, relative, generally, to a fluid state. The equilibrium properties have been calculated and are shown to agree very well with the corresponding properties of argon. It is concluded that, to a good approximation, the equilibrium state of argon can be described through a two-body potential. © 1967 The American Physical Society.
