摘    要:
本文采用稳式NND格式,通过求解三维薄层近似Navier-Stokes方程,数值模拟了飞船高超声速粘性流场。在计算中充分考虑了网格雷诺数和网格分布对计算结果的影响,不但得到了满意的表面压力、热流分布和流场的物理量分布,而且得到与实验观察一致的表面油流图像和分离结构。

关 键 词:高超音速流动 分离流动 宇宙飞船

Abstract:
The implicit NNDschemc developed by Professor ZhangHanxin is used to solve the thin-layer three-dimensional Number-Stokesequations.The influence of the CellRcynolds Number on the stagnationpoint heat transfer rate is seriously considered,and then the hypersonicfore-and afterbody flow fields over capsule-type vehicles are simulated.Using the appropriately clustered mesh,the numerical results predict thedistributions of the pressure and the heat transfer rate. The complicatedtopology of three-dimensional separations on the afterbody are also pre-sented.It is shown that these numerical results agree well with existingnumerical solutions and experiment data.
Keywords:hypersonic flow  space vehicles  NND scheme   separationflow   difference methods.
