Modern intense lasers offer the chance to experimentally probe environments similar to those that exist in complex astrophysical phenomena. In addition to providing observation of the behavior of matter in such environments, well-controlled experiments provide data with which to validate models and simulations. Simulations of experiments performed using the University of Rochester's Omega laser facility, which involve shock propagation through a multi-layer target, are being used as a validation test for the FLASH code, developed by the ASCI/ASAP Center for Thermonuclear Flashes at the University of Chicago. These multi-layer target experiments are designed to replicate the complex hydrodynamic instabilities thought to arise during supernovae explosions. In addition to validating the FLASH code, we seek to gain a better understanding of the turbulent mixing that occurs as a result of instabilities driven by the propagation of the shock through the layered target. We report on our progress to date on these simulations. This work is supported by the Department of Energy under grant B341495.
