| 摘 要： | 本文分析了一类高精度迎风TVD欧拉方程差分格式的精度,并用240×80个网格点进行马赫反射的计算,获得了目前实验和计算不易得到的两个激波三叉点的复杂波系结构。本文还研究了激波管上壁面对马赫反射的影响,并计算了轴对称扩张管道中激波的运动及激波与半球形障碍物的相互作用。计算结果分析指出,本文所采用的高精度迎风TVD格式与计算方法可以用来模拟具有复杂波系的工程问题研究。

| Abstract: | High resolution upwind schemes for solving the Euler equations were analysed and employed to simulate Mach reflection in a shock tube.Complex shock configurations including two triple points were captured successfully with 240X80 points.The effect of upper tube wall on Mach reflection was also considered.In addition, the interactions of moving shock on a semisphere obstacle in an expantion tube were calculated. The range of moving shock Mach number Ms is from 3.85 to 20.62 . |
