Contents I. Introduction
Several industrial systems involving gas flows at different scales of applications are in growth use. In the last few decades, lattice Boltzmann method was successfully used as a mesoscopic approach based on both continuum and kinetic descriptions of flows. Hence, LBM has become a recent powerful computational fluid dynamics (CFD) tool. Its popularity is mainly because the method can be extended to other applications unlike the Navier-Stokes based solvers restricted to the pure macroscopic description of flows.
