摘　　要：为实现超声速多相流动的高效数值仿真,搭建了多机集群分布式MIMD并行计算平台,并基于MPI通信平台开发了计算多相流流场的并行计算程序。对并行计算中网格分区方法、区域网格交界处通信方法及Euler与Larange坐标系间数据传递技术进行了研究。并进行了超声速燃烧多相流动算例的数值验证,比较了并行计算效率,证明了该多相流并行计算方法是高效可行的。For effective numerical simulation of supersonic multi-phase flow, the parallel calculation program of multiphase flow numerical simulation was developed by the MPI transfer function database, and the PC cluster distribution type system was established for MIMD parallel computation architecture. The method of grid partition, the course of grid sub-zone interface communication, and the data transfer between Euler and Lagrange coordinate system were studied. Then a case of multi-phase supersonic combustion flow was conducted to numerical validate, and the efficiency of parallel computation was compared. Which indicate the parallel numerical simulation method for multi-phase flow is viable and effectively.
