A DNS Study on Hypersonic Boundary-Layer Receptivity and a New Transition Control Strategy by Surface Roughness
Abstract
The objective of this proposal is to conduct computational and Linear Stability Theory (LST) based theoretical research on the fundamental mechanisms of hypersonic boundary-layer instability and receptivity in the context of the relationship between synchronization points and surface roughness location and their effects on transition control. Also the aim is to develop and validate a new passive transition control strategy using strategically-placed 2-D and 3-D surface roughness elements that is expected to enable AFRL researchers to use 3-D high order cut-cell code developed at UCLA to simulate a discrete boundary layer trip on HIFiRE-1 type vehicles.
