Title: Hydrodynamic Instabilities & Turbulence: A Journey Through Scales

ABSTRACT: Hydrodynamic instabilities such as Rayleigh-Taylor (RT) and Richtmyer-Meshkov (RM) instabilities usually appear in conjunction with the Kelvin-Helmholtz (KH) instability and are found in many natural phenomenon and engineering applications. They frequently result in turbulent mixing, which has a major impact on the overall flow development and other effective material properties. This can either be a desired outcome, an unwelcome side effect, or just an unavoidable consequence, but must in all cases be characterized in any model. Examples of the pivotal roles played by the instabilities in applications are given in the context of inertial confinement fusion, supernovae, pulsed-power experiments, scramjets, solar prominences, and ionospheric flows in space. The presentation is addressed to a broad audience, but with particular attention to graduate students and researchers that are interested in the state-of-the-art in our understanding of the instabilities and the unique issues they present in the applications in which they are prominent.
