【Abstract】 Generally,in the application of Lattice Boltzmann method(LBM),the decision of boundary conditions is a main point because the boundary conditions will affect the process and exactness of the numerical simulation by LBM.There are several methods,such as wall bounce back,normal bounce back and interpolation,to choose the boundary conditions for LBM.After studying the boundary condition application,it was found that different methods of deciding boundary conditions can be mixed to the application when one uses LBM to do the numerical simulation.更多还原
