摘要
本文采用求解NS方程的方法对战术导弹的流场进行了数值模拟。应用区域分割技术和拼接网格的并行策略 ,发展了一种适合于分布式存贮并行环境的隐式有限体积并行算法 ,在PVM并行环境下 ,对战术导弹绕流流场实现了单块网格多机并行计算和多块网格多机并行计算 ,通过负载平衡等方法得到了较高的加速比。
In this paper, the aerodynamic force and the flow field structure of the tactical missile were obtained by solving 3D NS equations.The domain decomposition technique and patch grid technique are used for parallel computation. The parallel numerical calculation on a distributed memory multiprocessors system with implicit finite volume algorithm is developed for three dimensional viscous flowfield. By balancing load,the high speedup has been obtained.The result of serial calculation and parallel calculation is identical.
