| 摘 要： | 本文回顾了自由来流扰动引起的边界层旁路转捩研究进展, 所讨论的自由来流扰动包含高湍流度自由来流和尾迹两大类. 首先介绍旁路转捩的定义、途经及其与规则转捩的区别; 继而讨论高湍流度自由来流引起旁路转捩的路径和机理, 涵盖感受性、瞬态增长、湍流斑、条带稳定性等旁路转捩的主要环节. 在此基础上介绍了尾迹引起旁路转捩的研究现状, 包括对流尾迹和大尺度钝体尾涡两种尾迹形式, 分析了转捩路径及机理, 最后给出研究展望.

| Abstract: | Progress in bypass transition induced by free-stream disturbance is reviewed in this paper.Freestream disturbance,as the forcing environment,can be divided into two categories,free-stream turbulence and wake.The definition,classification and general route of bypass transition is presented first,followed by reviewing the characteristics and physics of FST-induced bypass transition.In this scenario,the topics of receptivity process,transient growth theory,Klebanoff mode,streak instability,turbulent spot and b... |
