The Enskog-Vlasov kinetic equation for a dense fluid of spherical molecules interacting by Sutherland potential has been solved numerically to study the vapor-liquid equilibrium by a single kinetic equation. The equilibrium structure of the vapor-liquid interface has been obtained at various temperatures. The linear Enskog-Vlasov equation has also been used to describe the motion of a test particle crossing the vapor liquid boundary. The reemission probability of a gas molecule impinging on the liquid surface is obtained as a function of initial molecular velocity and system temperature.

Abstract

The Enskog-Vlasov kinetic equation for a dense fluid of spherical molecules interacting by Sutherland potential has been solved numerically to study the vapor-liquid equilibrium by a single kinetic equation. The equilibrium structure of the vapor-liquid interface has been obtained at various temperatures. The linear Enskog-Vlasov equation has also been used to describe the motion of a test particle crossing the vapor liquid boundary. The reemission probability of a gas molecule impinging on the liquid surface is obtained as a function of initial molecular velocity and system temperature.
