000014042 520__ $$2eng$$aThe Richtmyer-Meshkov instability arises when a shock wave interacts with an interface separating two fluids. In this work, high fidelity simulations of shock induced multi-material mixing between N2 and CO2 in a shock tube are performed for a Mach 1.55 shock interacting with a planar material interface that is inclined with respect to the shock propagation direction. In the current configuration, unlike the classical perturbed flat interface case, the evolution of the interface is non-linear from early time onwards. The computational domain is setup to match experiments performed by McFarland et. al. [4]. Simulations at multiple grid resolutions upto 4.3 billion grid points were performed on upto 65, 536 processors on the Blue Waters system. Comparison with experiments show that the simulations adequately represent the experimental results. Turbulence statistics before and after re-shock are presented.
