Front Tracking Simulations of Shock Refractions and Shock-Induced Mixing
We discuss the use of front tracking to simulate shock reflections and shock-accelerated interfaces. Our simulations of regular Mach reflection show enhanced resolution of the primary waves in the interaction, and our computations of the growth rate of a Richtmyer-Meshkov unstable interface are the first numerical results that are in quantitative agreement with experiments on a shocked air-SF6 interface. Previous computations of the growth rate of the instability produced values that were almost twice those found in experiments.
