A comparative study of approaches for modeling Rayleigh-Taylor turbulent mixing

This paper considers similarities and differences in the governing mechanisms and basic properties of Rayleigh-Taylor turbulent mixing as discussed in recent theoretical and heuristic modeling studies and briefly discusses how these mechanisms and properties may be explored in experiments and simulations. We were motivated by a number of stimulating questions, thoughtful comments and sagacious remarks by our colleagues and the anonymous referees, whose contribution to improving this work is warmly appreciated.
