- Abstract
- A representation of the forcing term in the Boltzmann equation based on a Hermite expansion of Boltzmann distribution function in velocity phase space is derived. Based on this description of the forcing term, a systematic omparison of previous lattice Boltzmann models describing a nonideal gas behavior is given.
