提出了一种快速的贴体网格生成技术,利用该技术生成的网格具有较好的正交性,可以根据几何参数、物理参数的分布控制网格的疏密。文中生成了典型的 H 型、C型、O 型网格。同时对平面叶栅跨音流动进行数值模拟,结果表明:该方法能显著减少计算量,生成的网格适合数值计算,对求解的精度、收敛性都具有优越性。 A fast ontology mesh generation technology is proposed. The grids generated by this technique have good orthogonality, and the density of the grid can be controlled according to the distribution of geometric parameters and physical parameters. The paper generated a typical H-type, C-type, O-type grid. At the same time, numerical simulation of transonic flow in a plane cascade is carried out. The results show that this method can significantly reduce the computational load. The generated grid is suitable for numerical calculation and has the advantages of both accuracy and convergence.
