The basic principle and the boundary conditions of the lattice Boltzmann method were studied.With this method,the flow field of flow around a single square cylinder at different Reynolds numbers was studied,and the critical Reynolds number and range of the Carmen vortex street produced by the square cylinder were explored,so that the correctness and convenience of the boundary processing and numerical simulation of the lattice Boltzmann method were verified. The flow field of parallel square cylinders with different distribution distances was simulated with Reynolds number at 200. The results showed that the interplay among the vortex around the square cylinder was the most obvious when the cylinder spacing was2 times the length of the square cylinder.
