| 摘 要： | 利用格子Boltzmann方法, 对主圆柱尾流区域内放置附属圆柱的绕流进行数值模拟. 结果表明: 放置单个附属圆柱时, 主圆柱所受阻力减小, 阻力
系数发生周期性改变; 放置两个附属圆柱的减阻效果更好.

| Abstract: | The flow around a main cylinder affiliated by cylinders in the near wake of the main cylinder was simulated by means of lattice Boltzmann method.It was found that the drag coefficient of the main cylinder with a single affiliated cylinder was decreased.The variant drag coefficient changed periodically.The drag coefficient of the main cylinder is further decreased if two affiliated cylinders were placed near the wake of the main cylinder. |

| Keywords: | lattice Boltzmann method affiliated cylinder flow around circular cylinder |
