摘要
通过对二维泊松方程增加伪时间项 ,采用时间推进法求解生成二维网格 ,利用拉格朗日插值生成三维网格 ,给出了一种在涡轮发动机复杂区域中生成结构化网格的计算方法。该方法很好地保证了网格的质量和正交性。
In order to create 3D calculation grid, 2D Poisson equation was solved by time matching method. It showed a numerical method to create structure grid of complex region in turbine engine. Orthogonality and quality of grid were provided by this method. The ability to simulate in detail of flow field would be improved by this method combined with domain decompose method.
