Properties of a multispeed lattice Boltzmann equation

摘要 A multispeed lattice Boltzmann equation with nine velocity directions on a two-dimension square lattice is investigated. In the macroscopic hydrodynamic equation, the coefficient before convective term becomes 1 and the viscosity can be decreased to zero. Computer simulation data are exactly coherent with theoretical results. A multispeed lattice Boltzmann equation with nine velocity directions on a two-dimension square lattice is investigated.
