Coarse grained simulation and dynamic bridging for turbulent mixing predictions

We revisit coarse-grained simulation strategies for turbulent material mixing driven by shocked/accelerated material interfaces, based on LANL's Radiation Adaptive Grid Eulerian (xRAGE)-Large-Eddy Simulation (LES), and dynamic bridging xRAGE LES and Besnard-Harlow-Rauenzahn Reynolds-Averaged-Navier-Stokes using Low-Mach-Corrected hydrodynamics. Tests of the new simulation paradigms demonstrate improved scaleresolving, enabling higher simulated mixing and turbulence levels on coarser grids. Impact assessments are carried out based on simulations of shock-tube experiments.
