Energy Conserving Discrete Equation for Non-Ideal Systems

Nicos Martys

Abstract

The BBGKY formalism is utilized to obtain a set of moment equations to be satisfied so as to obtain an energy conserving discrete Boltzmann equation for the case of a non-local interaction potential. A modified BGK form of the collision operator consistent with these moment equations is described. In the regime of isothermal flows a previous proposed non-ideal gas model is recovered. Other approaches to constructing the collision operator are discussed for implementation in numerical codes.
