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
