Abstract. The flow around a bluff body is a classical problem in the field of fluid mechanics, and its flow mechanism has obvious engineering application value. Numerical simulation is an effective means to solve the problem of flow around bluff body. In recent years, as a new numerical method, lattice Boltzmann method has been more and more concerned and applied in the simulation of complex boundary. Thus, the lattice Boltzmann method is suitable for simulating the flow around bluff body. In this paper, under different Reynolds numbers, numerical simulation is carried out of flow around a square cylinder based on lattice Boltzmann method. And the effect of Reynolds number on the flow around a bluff body is summarized.

Keywords: Reynolds number, lattice Boltzmann method, flow around square cylinders.
