A Molecular Dynamics Investigation of the Ratio of Ternary to Binary Collision Density in Nonideal Gases
Abstract
Abstract Using molecular dynamics simulations, the ratio of ternary to binary collision densities is investigated for both a hard-sphere gas and a Lennard-Jones gas. The simulations confirm the existing theoretical models for the hard-sphere gas but reveal temperature dependence of collision density ratio in a Lennard-Jones gas. A theoretical model is developed to explain this temperature dependence.
