Abstract:

The domain decomposition method and the parallel computing method are applied to a two dimensional Euler solver for transonic and supersonic flow using a PVM parallel environment. A zonal interface conservative technique based on flux vector splitting methods and characteristic theory is developed and applied to a two dimensional transonic and supersonic flow field including blunt bodies and airfoils. The results show that the zonal solution converges effectively and is in good agreement with the continuous single region solution. Parallel computing “First in First out” synchronization strategy is applied in a parallel programing mode. A higher parallel speedup ratio can be obtained if the overhead of communication is smaller and parallel computing load balancing is maintained well.
