摘要
提出了一种正交网格的生成方法．通过调整边界点的位置而不是修正 ξ和η的值来达到正交的目的；通过调整 ξ和η的疏密从而达到控制网格疏密的目的．在内燃机冷却通道及水轮机尾水管上生成正交网格，得到满意的结果，从而证明该方法是可行的．
A new method for the generation of orthogonal curvilinear co ordinates is presented. The positions of boundary points in physical domain are adjusted to obtain orthogonal curvilinear grids without changing the value of ξ and η . Good results are achieved in the applications of this method to the cooling system and to the draft tube of water turbine.
