在过去的十年中，许多研究工作者对激波管中正激波与边界层之间的相互作用进行了研究。由于需要了解这种现象可能对反射激波和管端之间区域的流动特性产生的影响，所以引起了人们的兴趣。这个所谓的反射激波区在化学动力学研究中很重要，也是高超音速激波风洞的气体储存区。本文综述了对这一问题的各种分析以及实验研究的结果。反射和透射激波分叉，分叉脚的增长率，和过渡到湍流的影响进行了讨论。分叉的影响，在激波管中的流动进行评估，特别是作为一种机制，用于运输冷驱动气体的端板，导致早期冷却的气体上的反射激波区域。
During the last decade the study of the interaction between normal shocks and boundary layers in the shock tube has been carried out by many research workers. This interest has been fostered by the requirement to understand the effects that this phenomenon may have on the flow properties in the region between the reflected shock and the end of the tube. This so‐called reflected shock region is important in chemical kinetics studies and as a reservoir of gas for hypersonic shock tunnels. In this paper a review is given of the various analyses of the problem together with the results of experimental studies. Reflected and transmitted shock bifurcation, the rate of growth of the bifurcated foot, and the effects of transition to turbulence are discussed. The influence of bifurcation on the flow in the shock tube is assessed, especially as a mechanism for transporting cold driver gas to the end plate, causing early cooling of the gas on the reflected shock region.
