摘要 把已有的串行数值模拟程序改编成消息传递接口(MPI)下并行环境的并行数值模拟程序,模拟了基于NASA-TP1680单级透平的4种不同组合的流场,验证了并行程序的有效性和较好的并行效率.同时,分析了影响并行效率的主要因素. An existing serial computational fluid dynamics (CFD) program was modified to a parallel simulation program based upon message passing interface (MPI). Four flow fields of different combinations for NASA-TP1680 single-stage turbine were simulated to validate the accuracy and parallel efficiency of the parallel program. The major influential factors to the parallel efficiency were also analyzed.
