激波反射现象的研究进展

本文依据激波反射研究领域最近十几年的研究热点问题,回顾了激波反射现象的主要研究成果,并着重介绍了以下几个方面的最新研究进展:弱激波的反射结构、运动激波反射的各种反射结构及转变准则、定常激波反射波形结构的分析以及激波反射的迟滞现象等.考虑到三维激波反射重要的工程应用需求,本文还介绍了三维激波反射的研究进展与目前存在的问题.最后,作者从激波动力学的视点出发,探讨了激波反射方面未来的学科发展方向和需要深入研究的问题.

ADVANCES IN SHOCK WAVE REFLECTION PHENOMENA

Advances in the study on shock wave reflection phenomena are reviewed.Some aspects of the advances are particularly elaborated in accordance with the research focuses of shock wave reflection phenomena in the past decade: weak shock reflection,wave configurations and transition criteria of nonstationary shock wave reflection,wave configurations of steady shock wave reflection,and the hysteresis of shock wave reflection.In view of their significances in practical applications,the advances in three-dimensional shock wave reflection phenomena are also presented and the problems confronted are discussed.In the mean time,directions of further studies on shock wave reflection are suggested.
