Rayleigh-Taylor Turbulence Nothing Like Kolmogorov

by Olivier Poujade arXiv.org E-print Archive, 15 Jun 2006 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 `a 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. Read more
