摘    要:本文采用区域分割技术和拼接网格的并行策略,发展了一个适合于分布式存贮多机系统的TVD隐式有限体积并行算法;并在PVM并行环境下,对三维高超音速绕流流场实现了多机并行计算,通过负载平衡等方法得到了较高的加速比(在二处理机系统上加速比为1∶84,在四处理机系统上为3∶44)。

关 键 词:TVD隐式格式,三维高超音速流场,多机并行计算

Abstract:In this paper, the domain decomposition technique ( DDT ) and the parallel strategy of patched grid are used. The parallel numerical calculation on multiprocessors with TVD implicit finite volume algorithm is carried out for three dimensional hypersonic viscous flowfield by balancing load. The high speedup (the speedup is 1 84 on two processors and 3 44 on the four processors ) has been obtained.
Keywords:TVD implicit scheme  3D hypersonie flowfield  Multiprocessors parallel calculation
