Entropic lattice Boltzmann models for hydrodynamics in three dimensions

Chikatamarla, S.S., Ansumali, S. and Karlin, I.V. (2006) Entropic lattice Boltzmann models for hydrodynamics in three dimensions Physical Review Letters, 97, (1), 010201-[4pp]. (doi:10.1103/PhysRevLett.97.010201).

Record type: Article


Efficient, nonlinearly stable entropic lattice Boltzmann models for computational fluid dynamics are presented. A new method of fast evaluation of equilibria to machine precision is proposed. Analytical solution is found for the collision step which guarantees stability and thermodynamic consistency of the scheme. As an example, a novel 15-velocity lattice Boltzmann model is derived and validated with a simulation of a three-dimensional backward-facing step flow.
