| Abstract: | In recent years, the lattice Boltzmann method (LBM) has been developed into an alternative and promising numerical scheme for simulating fluid flows and modelling physics in fluids. The LBM has achieved great success in solving numerous problems in many areas. In this paper, we introduce Lattice Boltzmann method and its basic principle and its application, that is a efficient modeling numerical algorithm for complex fluid flow. two numerical simulation results illustrate that Lattice Boltzmann method is right, effective, that shows a wide application prospect to us, which probably provides the bases of intensive research and extensive applications later on. |
