Learning about Modal Decompositions of Hypersonic Boundary Layer - Shock Interactions from Kinetic Petascale Simulations

Deborah Levin, University of Illinois at Urbana-Champaign

Usage Details

The specific research problems that we wish to continue applying the SUGAR DSMC code to are the 3-D simulations of shock-shock and shock-boundary interactions for moderate Mach number flows over double wedges and double cones. These geometries exhibit Edney Type IV and V strong shock interactions that include the attached, oblique shock formed over the first wedge structure, the detached bow shock from the second surface, the separation of flow on the first wedge resulting in the separation zone, separation shock, and the reattachment shock that cause complex features such as the triple point, λ-shocks, and sometimes even the KH instabilities in the shear layer.
