求助Rayleigh–Taylor, Richtmyer–Meshkov 等的概念

suhuoyi212

At later stages, shock–flame interactions,
Rayleigh–Taylor, Richtmyer–Meshkov and Kelvin–
Helmholtz instabilities, and flame–vortex interactions in
obstacle wakes become responsible for the increase of the
flame surface area, the energy-release rate, and, eventually,
the shock strength
这里的Rayleigh–Taylor, Richtmyer–Meshkov and Kelvin–
Helmholtz  3个概念是什么意思啊 谢谢指教

是三种动力学不稳定的名词，大致解释如下，严格的解释可以去查书。
Rayleigh–Taylor不稳定主要是由于重力所导致的界面的不稳定；
Richtmyer–Meshkov不稳定是由瞬间冲击（如激波）所导致的界面不稳定；
Kelvin–Helmholtz不稳定是由界面之间剪切力或速度差所导致的不稳定。
