摘　　要：本文在LU SGS方法求解可压缩Navier Stokes方程的串行程序基础上 ,发展了适合MPP系统类型的并行计算机的并行算法程序 ,并针对双三角翼大迎角绕流问题 ,就不同的并行计算方法进行了对比研究 ,探讨了优化并行策略 。Based on a serial computational code for the solution of Navier Stokes equations, a parallel computational code is developed in this paper, which is applicable to the MPP type parallel computers. The flow past a double delta wing at high angles of attack is numerically simulated by using this pa rallel computational code and the comparisons between the results using different parallel techniques are conducted to investigate the optimal parallel strategy and to examine the computational efficiency and the acceleration ratios.
