| 摘 要： | 数值网格生成方法的基本思想是通过交换方程，把物理空间上不规则域交换成计算空间上规则而简单的区域．数值网格生成方法的发展，扩展了有限差分法的适应条件．在总结前人工作的基础上，本文提出一种生成复杂边界三维贴体网格的耦合方法，拓展了一般三维贴体网格的应用范围．通过实例验证，该方法切实可行．使用方便，对复杂边界三维区域的流场计算有重要的参考价值。

| Abstract: | For applied limit of 3-D body-fitted curvilinear coordinate transformation,this paper presents an improved method in order to form 3-D body-fitted grid for complex boundary.It combines 3-D body-fitted coordination transformation with 2-D body-fitted coordination transformation.The given examples show that the flow field to possess irregular boundary may be accurately solved.No doubt,it is beneficial to calculating flow field in complex 3-D domain. |
