摘　　要：通过对串行分块SIMPLE算法的扩展 ,提出了一种分区并行算法 .利用自行建立的两 (多 )台主机并行计算平台 ,对平板驱动空腔流动与绕“CFD”流动进行了分区并行计算 ,与串行计算的结果对比表明 。A parallel computing method for complex flows is developed based on the corresponding serial domain decomposition SIMPLE algorithm. Two turbulent flows, the lid driven cavity flow and the flow around 'CFD' ,are computed using this method on a two PC cluster. Comparison between parallel and serial computing results shows satisfactory parallel speedup and efficiency for complex flows.
