| 摘 要： | 本文采用时间相关法和隐式推进迭代方法求解了绕ＨＥＲＭＥＳ外形高超声速无粘流动。将抛物型方程和代数方程相结合生成计算网格，既节省了网格生成的时间，又能得到较合理的网格分布。在时间相关法计算中，采用了显式ＮＮＤ格式；在隐式推进迭代计算中，采用了推广的隐式ＮＮＤ格式。

| Abstract: | The hypersonic inviscid flow around the HERMES config-uration has been simulated by the time-dependent algorithm and implicit spatial-marching itcration algorithm in this paper.The parabolic cquations are combined with the algebraic equations to generate the computational grids, and the reasonable grids distribution can be obtained with less computationaI time. The explicit NND schemes arc used in thc time-depcndent calculation and the implicit NND schemes are used in the im-plicit spatial-marching iteration calculation. |
