摘　　要：使用表面涡法研究高雷诺数下不同排列方式双圆柱绕流的流动状态．计算了双圆柱在并列、级列的情况下的各种流动结构，涡街的变化及作用在圆柱上的受力情况．计算结果清楚地描述了双圆柱绕流复杂的流动状况，与实验显示的流动状况十分相似，斯特罗哈数与阻力系数均与实验结果相符．The flow around two circular cylinders in various arrangement in high Reynoldsnumbers is numerically simulated based on vortex method, which are arranged in side by side and staggered. The results are similar to the experimental ones. Strouhal number, the lift coefficient and the drag one are in agreement with the experimental results, too.
