为深入理解超声速飞行器和动力系统流场中存在的激波反射迟滞现象,对近年来有关定常激波反射迟滞文献资料进行了调研和总结。回顾了定常激波反射迟滞现象的提出与证实过程,介绍了改变入射激波形状、改变下游波系结构等可引起激波反射出现迟滞的实现方式,并对粘性效应、三维效应和动态效应等影响激波反射迟滞现象的因素进行了探讨,对激波反射迟滞现象的研究热点和难点问题进行了分析与总结。
In order to further understand the shock reflection hysteresis existing in the flow field of supersonic aircraft and power system, the literature about the reflex hysteresis of constant shock wave in recent years has been investigated and summarized. In this paper, we review the process of proposed and confirmed the phenomenon of retarded hysteresis of a constant shock wave, and introduce the ways to change the shape of the incident shock wave and change the structure of the downstream wave system, which can cause the hysteresis of shock reflection. The viscous effect, three-dimensional effect and dynamic effect The factors influencing the hysteresis of shock wave reflection are discussed. The hot and difficult problems of shock reflection hysteresis are analyzed and summarized.
