Rayleigh instability

WebRayleigh-Ta ylor Instability some initial conditions in (perhaps unstable) equilibrium, assume a small perturbation to those conditions, and observe the results: if the perturbation grows with time then an instability is indicated. One such scenario is the Rayleigh-Taylor Instability: given two media WebBasic fluid equations are the main ingredient in the development of theories of Rayleigh–Taylor buoyancy-induced instability. Turbulence arises in the late stage of the instability evolution as a result of the proliferation of active scales of motion. Fluctuations are maintained by the unceasing conversion of potential energy into kinetic energy. …
