| 摘 要： | 本文提出了一科简单有效的计算方法,用于模拟绕任意形状二维物体的高Reynolds数空泡型分离流场。基于流场边界层在其分离点处不断向下游释放小旋涡这一物理概念,根据涡量沿流程的分布并结合外部势流场的计算确定分离区边界,大大改善了空泡边界迭代的收敛性。

| Abstract: | A new method is proposed to calculate high Reynolds number cavity flow a two-dimensional body of arbitrary shape. Based on the concept of vortex shedding at the separation point of a flow from its boundary layer to the downstream region, velocity distribution on the cavity boundary is obtained by correlating the flow velocities with the vortitity on the separation boundary, thus the contour of the cavity can be determined by coupling this distribution with that obtained from flow calculation. With the method presented in the paper, the convergency of cavity-boundary iteration is improved greatly. |
