摘要
利用有限差分方法求解变截面激波管中存在激波的二维流体流动问题。着重研究初始流场为静止和超音速两种情形。分析讨论所得计算结果,并和已有实验结果进行了比较。
The finite difference method (FDM) is used in the present paper to solve the two-dimensional fluid flows for the case of shock's motion in a section-changed shocktube. Two kinds of fluid flows are investigated, which correspond to the static and supersonic initial flow conditions respectively. Numerical results are analysed and compared with existing experimental ones.
