超声速射流逆流通常用于导弹、航天飞机、卫星和飞船等飞行器运动状态的控制。欠膨胀超声速射流逆流的流场包含有多激波（如弓形激波和马赫盘）、接触间断和剪切层，其结构非常复杂。本文采用激波高分辨率有限差分（ＴＶＤ）格式，对恒定自由流条件，各种不同射流出口压比的超声速轴对称道射流进行了数值模拟，且对各种条件下的物理现象给予了分析。计算的马赫盘和弓形激波位置与实验值相吻合，为此类流动问题提供了一种有效的预测方法。
Supersonic jet countercurrent is commonly used to control the movement of aircraft such as missiles, space shuttles, satellites and spacecraft. The owed supersonic jet flow contains multiple shocks (such as arcuate shocks and Mach plates), contact discontinuities and shear layers, and its structure is very complex. In this paper, we use the shock wave high resolution finite difference (TVD) format to simulate the supersonic axisymmetric jets with constant free-flow conditions and various jet outlet pressure ratios. The physical phenomena under various conditions are also analyzed. The calculated positions of Mach disk and bow shock coincide with experimental values, which provides an effective prediction method for such flow problems.
