- Title
Bulk turbulent transport and structure in RayleighTaylor, RichtmyerMeshkov, and variable acceleration instabilities.

- Abstract
Directed energy and turbulence structure are shown to be crucial in understanding the growth of self-similar RayleighTaylor and incompressible RichtmyerMeshkov turbulent mixing zones. Averaging over the mixing zone is used to analyze the response of a modified kε model and a turbulent two-fluid model. Three different transport regimes are then identified by considering self-similar variable acceleration RT flows (SSVARTs), which appear as promising reference flows for model testing.
