摘　　要：本文采用离散涡方法计算了大雷诺数下线性剪切流绕圆柱的分离流动,计算结果给出阻力系数、横向力系数、边界层分离点、斯特罗哈数及尾流中旋涡的分布图案,计算数据与已有的实验数据相吻合。A flow around a circular cylinder in a uniform shear flow at high Reynolds number is numerically investigated by the use of the discrete vortex- approximation. The drag coefficient, lift coefficient, Strouhal number, poaitions of separation point and vortex patterns are given by this calculation. They are reasonable and in Agreement with experimental results.
