Abstract

Direct statistical comparison of hydrodynamic mixing experiments and simulations W. Rider % J. Kamm', P. Rightley', K. Prestridge', R. Benjamin', P. Vorobieff^ ^Los Alamos National Laboratory, Los Alamos, USA ^University of New Mexico, Albuquerque, USA Abstract Fluid mixing phenomena are dominated by irregular structures induced by flow instabilities, which lead to non-deterministic behavior. Hence, there is no direct, pointwise method to establish the correspondence between experimental data and numerical simulation. Using statistical analysis methods, we examine the correspondence between experimental data and simulations. We examine the detailed structures of mixing experiments and their simulation for the Richtmyer-Meshkov (RM) instability. To examine the compressible RM instability, we use the gas curtain experiment of Rightley et al. [8]. Numerical simulations of both experimental config- urations were conducted with a variety of flow codes. The experiment and simulation a
