一种适体坐标下复连通区域的流场数值计算方法
A flow numerical computation method of multiply-connected region in body-fitted curvilinear coordinate systems
【摘要】 本文介绍了一种简便地处理复连通域内流场数值计算问题的方法 :将复连通域分解成多个单连通域 ,分别进行网格划分 ,再组合还原 ,通过网格变换系数将地形对流场的影响带到流场计算过程中去 ,完成流场计算
【Abstract】 In this paper, a simple method was introduced to compute the flow field in a multiply connected region. Firstly, the multiply connected region was divided into several simply connected regions. And then grid was generated in each simply connected region. Finally, all the grids were combined together. And the flow computation field action with the grid transformation coefficients.
