摘要
本文分析了圆柱坐标体系下的非轴对称的极点问题的产生原因,总结了国内外研究者在极点问题上的处理方法,通过采用特殊网格的方法,改变极平面上的网格形式和极点处的的速度形式,以克服在极点上对流和扩散的传输问题。
The article analyzed the reasons for singularity in axis in numerical simulation of three dimensional dissymmetry flows, and summarized the ways to deal with this singular question in domestic and abroad. By using special grid and changing structure of meshes and velocities in singular point, the convection and diffuseness in singularity could be resolved.
