Title:
Roughness-induced Boundary-layer Transition on a Hypersonic Capsule-like Forebody including Nonequilibrium 
Abstract:
The present work investigates the influence of high-temperature gas effects on the laminar-turbulent transition induced by a patch of distributed roughness on a hemispherical capsule-like geometry. The freestream conditions correspond to a realistic reentry scenario at Mach 20. At these conditions, chemical reactions and nonequilibrium effects are present in the high-enthalpy boundary layer of the hemisphere. Parallel Direct Numerical Simulations are undertaken to analyze the instability mechani...    »
