摘要
提出了在贴体坐标系中非交错网格的ＳＩＭＰＬＥ 算法，通过对控制界面上的逆变速度分量作特殊加权平均处理，可避免在非交错网格中产生压力波动而连续性方程又无法检测出来的问题．
SIMPLE algorithm with non-staggered gird in the body-fitted curvilinear coordinate system is proposed. The pressure oscillation which can't be tested by continuity equation is prevented by means of a special averaging procedure of contravariant velocity components on control volume faces.
