摘要 本文采用有限体积的ＮＮＤ格式，数值模拟了弹身超音速有攻角绕流，分析了周向网格和法向网格对弹身背风区分离流态及气动性能的影响，计算与实验结果比较，两者相当一致。 The supersonic vortical flow about a missile body has been simulated with a finite volume NND scheme in this paper. The effect of the grid density on results is studied. Computed results are coincident with experimental results.
