Lattice Boltzmann method based model for fluid flow simulations.

Lattice Boltzmann Method (LBM) is very much popular for fluid flow applications due to its capability of implementing the physics of the problem as well as simple explicit governing equations unlike to implicit Navier-Stokes governing equations. LBM is extensively used in single and multiphase fluid flow problems. LBM based multiphase and multi component fluid flow analysis models have got wide acceptability amongst all CFD (Computational Fluid Dynamics) tools nowadays. In this paper we propose a LBM based model for Lid driven cavity problem. Main purpose behind our study is to showcase the capabilities and benefits of LB based model against well-established Navier-stokes based solvers. Benchmark problem of Lid driven cavity and 2-D channel flow are solved and numerical results are shown in the paper. Numerical results are in nice agreement with well-established experimental and conventional NS based numerical results. [ABSTRACT FROM AUTHOR]
