摘要：

The flow around four cylinders in a square configuration with a spacing ratio 4 and Reynolds number of 200 are investigated using lattice Boltzmann method for angles of incidence alpha=0 and 45 degrees, respectively. The results show that no biased flow occurs and the flow pattern is symmetrical at alpha=0, and the vortex shedding exists after the upstream cylinders which is completely different from the experimental results. It is hard to explain the discrepancy at present. The phenomenon of vortex shedding in-phase observed in the experiment reappears in the numerical simulation at alpha=45 degrees.
