摘要
流体数值模拟计算中,有限差分法和有限体积法使用相对较多,但在复杂区域的计算时,需要生成曲线网格。文章对二维贴体网格的基本原理作了介绍,并针对目前常用的几种典型网格生成方法进行了比较;分析表明,对于所选择的物理域形状,根据势流理论得出的方法更为优越。
In the computation of fluid dynamic fields, finite difference methods and finite volume methods are usually used, but it is necessary to generate curvilinear grids in computing complicated areas. In this paper, the general principle of generating 2D body-fitted grids is introduced, and some typical grid-generating methods which are used currently are compared. The analysis shows that the method based on the potential theory is more effective in some selected physical areas.
