本文介绍了高性能并行计算在CFD数值模拟中的应用.CFD高性能并行计算可扩大求解规模,加快求解速度,是CFD实现高效计算的必然发展趋势.本文通过“数值风洞”的概念分析了CFD高性能计算的应用前景及对高性能计算的需求.通过某乘波飞行器前体并行算例对8～256CPU的CFD大规模并行效率和加速比进行了分析,并将CFD并行计算应用于高温热化学非平衡的返回舱数值计算中.%High-performance parallel computation for CFDCComputational Fluid Dynamics) numerical simulation is introduced in this article. The CFD high performance parallel computation expands the solving scale, accelerates the solution, which is the necessary development tendency for efficient CFD computation. Numerical windtunnel conception is illustrated to explain the CFD application prospect and its demand for high-performance computation. Based on Fortran and MPI, the CFD parallel computation program is developed. The CFD massive parallel computation with 8-256 CPU is carried out for waverid-er forebody on MPP parallel systems, and the parallel efficiency and speedup are analyzed. Finally the program and method are used for high temperature thermochemical non-equilibrium capsule flow computation.
