Abstract

Vortex bi-layers and “Vortex Projectiles” (VPs) are the essential coherent structures which emerge in the shock accelerated inhomogeneous (Richtmyer-Meshkov) flows, in particular the light (s/f/s) planar curtain configuration. In our visiometric mode of working, we identify and quantify several vortex processes which emerge in 2D simulations during four time epochs. In particular: large positive and negative secondary circulations that arise from incompressible baroclinic processes; upstream and downstream moving VPs; and an intermediate stratified decaying turbulent sub-domain containing VPs.
