| 摘 要： | 本文以数值方法研究了运动激波绕射矩形突台的非定常流场发展过程。计算中采用ＴＶＤ格式，得到了清晰的流场变化图谱。从流场图中可分辨出旋涡的形式过程及分离域形态。研究结果表明，本方法可以很好地描述激波绕射方台形成的复杂流动过程，对流场间断有较高的捕获力。

| Abstract: | A process of a shock wave diffraction over a rectanguler block is investigated by numerical simulation in this paper.Aset of the unsteady flow field isopycnics are obtained clearl The result of incident normal shock impinging on a wedge is cornpared with experimen,agood agreement is shown. The TVD scheme is used in this computa-tion,higher resolution of shock wave and flowfield discontinues are shown in computation results. |
