Title:
Investigation of vortical structures in the wake of pseudo-random roughness surfaces in hypersonic reacting boundary-layer flows 
Abstract:
The role of acoustic-perturbation in the laminar-turbulent transition of hypersonic flows is an important aspect of understanding the physical mechanisms of the transition process. This investigation uses Direct Numerical Simulations (DNS) in a re-entry scenario of an Apollo-like space capsule. Vortical structures in the wake of the roughness patch interact with an acoustic perturbation derived from local one-dimensional inviscid (LODI) relations. This study uses two different roughness structur...    »
