Turbulent mixing and beyond: non-equilibrium processes from atomistic to astrophysical scales II.

S I Abarzhi¹, S Gauthier, K R Sreenivasan.

Abstract

This Introduction summarizes and provides a perspective on the papers representing one of the key themes of the 'Turbulent mixing and beyond' programme--the hydrodynamic instabilities of the Rayleigh-Taylor (RT) and Richtmyer-Meshkov (RM) type and their applications in nature and technology. The collection is intended to present the reader a balanced overview of the theoretical, experimental and numerical studies of the subject and to assess what is firm in our knowledge of the RT and RM turbulent mixing.

Keywords: Rayleigh–Taylor instability; Richtmyer–Meshkov instability; high-energy-density physics; instabilities of plasmas and fluids; interfacial transport; turbulent mixing
