Shockwave Boundary Layer Interactions

In collaboration with J. Little and H. Fasel University of Arizona

Funded by AFOSR through University of Arizona subcontract

The recent renewed interest in hypersonic flows is motivating research aimed at improving the physical understanding of swept turbulent Shock wave Boundary-Layer Interactions (SBLI). Implicit Large-Eddy Simulations are being carried out in support of wind tunnel experiments at the University of Arizona.
