NASA / CR-2002-211660 ICASE Report No . 2002-20 Multiple-relaxation-time Lattice Boltzmann Models in 3 D

This article provides a concise exposition of the multiple-relaxation-time lattice Boltzmann equation, with examples of fteen-velocity and nineteen-velocity models in three dimensions. Simulation of a diagonally lid-driven cavity ow in three dimensions at Re = 500 and 2000 is performed. The results clearly demonstrate the superior numerical stability of the… CONTINUE READING
