摘要 　简要介绍了一种新的二维网格技术———九分笛卡尔网格技术.与传统方法将一个网格等分为4个不一样,该方法将一个网格单元等分为9个.同时考虑各向同性和各向异性加密,能够对激波和壁面附近进行快速加密,并且有效节省了网格点数目.用此方法计算了单个翼型、多个翼型及直管道下壁面带凸包的无粘带激波的流动. An automatic Nonet\|Cartesian grid method is presented together with Euler solutions of flows around complicated geometries. Grids are generated automatically by the recursive subdivision of a single cell into nine subcells for isotropic Nonet\|Cartesian grids and into three subcells independently in each direction for anisotropic Nonet\|Cartesian grids, encompassing the entire flow domain. The grid generation method is applied here to steady inviscid shocked flow computation. Results using this approach demonstrate that this method provides a simple and accurate procedure for solving flow problems with shock waves.
