Abstract:

Highperformance parallel computation for CFD(Computational 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 waverider 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.

Key words: highperformance computation；parallel computation；CFD；aerodynamics；numerical simulation
