| Abstract: | 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. |

| Keywords: | aerospace propulsion system message passing interface(MPI) parallel program parallel efficiency numerical simulation |
