| 摘 要： | 建立了基于区域分解的并行计算方法，将已有的后台阶喷管内流场三维ＴＶＤＭａｃ－Ｃｏｒｍａｃｋ显式格式的串行计算程序改造成为并行程序，获得了较高的并行加速比。并行计算结果同串行结果进行了对比，证明计算是成功的。

| Abstract: | A parallel algorithm based on domain decomposition methods was used to solve the 3 D N S equations for a kind of step nozzle flow.Traditional sequential codes of TVD MacCormack algorithm were modified to parallel ones in order to work in the Dawning 1000 parallel computer.A master slave model of PVM was used to control the calculation process.Fine acceleration ratio is acquired and the parallel results are accordant with the sequential ones |
