【Abstract】 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.更多还原
