摘　　要：提出用Ｄｅｌａｕｎａｙ三角化方法生成非结构网格的一种过程．所生成的网格可用于复杂多连通域内的可压流计算．采用Ｅｕｌｅｒ方程和格心有限体积法，研制出程序，给出了算例．A procedure of generating 2-D unstructured grids with Delaunay triangulation is proposed.The grid generated can be used to computation of compressible flow in complex multiply-connected domains.A computer code for now computations with the use of Euler equations on unstructured grid by finite volume method of cell-centred formulation is then developed.Some of the computation results are given.
