Solution of Two-Dimensional Lid-Driven Transient Cavity Flow Based on SIMPLE Algorithm

采用SIMPLE算法分析二维顶板驱动方腔内流动问题,介绍以这一算法求解方腔流动问题中所应用的流场控制方程与计算域离散、网格构建、边界条件处理的基本技术.所得到的结果与涡量-流函数法求解同一问题的计算结果进行了对比,并讨论了这两种方法的异同点.

The two-dimensional lid-driven cavity flow problem is simulated based on SIMPLE algorithm,the basic techniques are introduced to discretize the governing equations of the flow fields and computational domains,to create the grids,to dealing with the boundary conditions in solutions of the cavity flow problem with the algorithm.The results by this algorithm are compared with those by the vortex stream function method,and the differences and similarities between the two algorithms are discussed.
