Rayleigh-Taylor turbulence is nothing like Kolmogorov turbulence in the self similar regime
Olivier Poujade
Abstract
An increasing number of numerical simulations and experiments describing the turbulent spectrum of Rayleigh-Taylor (RT) mixing layers came to light over the past few years. Results reported in recent studies allow to rule out a turbulence à la Kolmogorov as a mechanism acting on a self similar RT turbulent mixing layer. A different mechanism is presented, which complies with both numerical and experimental results and relates RT flow to other buoyant flows.
