| Abstract: | Multi-Relaxation-Time Lattice Boltzmann Method(MRT LBM) is of better numerical stability and has attracted more and more research interests.The previous MRT LBM included artificial compressible effects.To overcome the disadvantage,an incompressible MRT LBM has been proposed in two dimensions recently.In this article,we present incompressible MRT LBMs in 3-D space,with example of nineteen-velocity.The equilibria in momentum space are derived from an earlier incompressible Lattice Bhatnagar-Gross-Krook(LBGK) ... |
