Abstract

In this study we propose a new experimental and methodological approach dedicated to the analysis of the development of a turbulent mixing zone produced by the Richtmyer-Meshkov Instability. A brief description of the experimental device dedicated to the generation of the initial interface is first presented. An overview of the main results obtained by means of strioscopic, Particle Image Velocimetry (PIV) and tomoscopic time-resolved measurements are then provided. The spatio-temporal evolution of the macroscopic scale based on the thickness of the mixing zone is discussed on the basis of the time-resolved Schlieren data. A first step into a more comprehensive analysis of finer, local scales of the flow is introduced, based on the qualitative analysis of the velocity and density fields during the development of the mixing zone.
