本文介绍了任意网格系统中的SIMPLE算法的推导过程,并将此算法应用于二维非结构化网格(三角形网格)之中,网格由DELAUNAY三角化方法生成.对顶盖驱动空腔流的计算表明该算法是令人满意的.
This paper introduces the derivation of SIMPLE algorithm in arbitrary grid system, and applies the algorithm to two-dimensional unstructured grid (triangular grid). The grid is generated by DELAUNAY triangulation method. Calculations of the cap-driven cavity flow show that the algorithm is satisfactory.
