| 摘 要： | 在离散涡方法中应用随机微分方程理论来求解二维钝体绕流问题，通过对静止圆柱不同雷诺数下的绕流计算，得到冯卡门涡街和回流区对称轴线上径向速度分布以及升力系数和阻力系数，都与已知结论非常一致。

| Abstract: | The theory of stochastic differential equation is employed in the discrete vortex method to solve the problem of two dimensional flow past a bluff body. The Von Karman Vortex Street, the distribution of radial velocity on the wake axis, and the coefficients of lift and drag are obtained by the present method in the calculation about two dimensional flow past still cylinder at several Reynolds numbers. The obtained results are in good agreement with those reported in the published literatures. |
