网格生成技术是流体机械内部流动数值模拟中的关键技术之一，直接影响数值计算的收敛性，决定着数值计算结果最终的精度及计算过程的效率；本文在分析大量文献的基础上，首先，对流体机械CFD中的网格生成方法即结构化网格、非结构化网格、混合网格进行了比较全面的总结，系统地分析这些网格划分方法的机理、特点及其适用范围；其次，对特殊的网格生成技术，如曲面网格生成技术、动网格技术、重叠网格生成技术、自适应网格技术进行了阐述；再次，指出了良好的网格生成方法应具备的特点；最后提出了网格生成技术的发展趋势。
英文摘要：
Mesh generation technology is one of the critical technology for fluid machinery flow numerical simulati-on,and directly influence the astringency of numerical simulation, which has an important effect on the numerical simulation results, final precision and the efficiency of computational process. On the basis of analyzing a great deal literatures, firstly, mesh generation methods and theory of fluid machinery are comprehensively summarized such as structured mesh, unstructured mesh, hybrid grid and respective relative merits and the principle, characteristes and scopes of these methods were systematically analysed. Secondly,Special mesh generation method were summarized, such as surface meshing, moving grid, adaptive grid and especially introduced the principle and application areaof adaptive grid. Thirdly, the characteristic of mesh generation method were pionted out. Finally,the trends of mesh generation are presented, and the tremendous difference is analyzed in mesh automatic generation at abroad and the necessary of exploiting CFD software and researching the mesh automatic generation technique in our country are put forward.
