REVIEW ON THE INSTABILITY STRUCTURE IN COMPRESSIBLE BOUNDARY LAYERS AND MIXING LAYERS AND ITS APPLICATION

本文回顾了可压缩边界层与混合层中失稳结构及其应用的研究进展.这些工作包括人们对高超声速平板边界层失稳特性、高超声速圆锥边界层转捩攻角效应的产生机制和可压缩混合层失稳特性的研究认识,以及这些相关认识的3个应用方向.这些相关工作丰富了人们对高速流动转捩和湍流拟序结构的认识.

This paper reviews the studies on instability structures in compressible boundary layer and mixing layers and their applications. These include the instability in hypersonic plane boundary layers, the mechanism of the effect of angle of attack on the hypersonic boundary layer transition on sharp cone and the instability in compressible mixing layers. All of these results are helpful for people to understand the transition process and turbulent coherent structure in high speed flows.
