Numerical Simulation for Flow over two Circular Cylinders in Micro Channel with Lattice Boltzmann Method

摘要：

　　For indepth study on flow characteristics for fluid bypass obstacles in micro-channel,the Lattice Boltzmann Method (LBM) was used to simulate fluid flow over two circular cylinders in side-by-side arrangement of a micro-channel.The velocity distribution and recirculation zone length under different Reynolds numbers (Re = 0~100) and different spacing ratio (H/D= 0~2.0) were obtained.The results show that the pattern of flow and the size of recirculation zone in the micro-channel depend on the combined effect of Re and H/D.
