Abstract:
In this report, our research accomplishments are summarized in the DNS study on hypersonic boundary-layer receptivity and a new transition control strategy by surface roughness 1 DNS study and PSELST based theoretical analysis on the fundamental mechanisms of hypersonic boundary-layer instability and receptivity in the context of the relationship between synchronization points and surface roughness location, together with the effects of nose bluntness and thermo-chemical non-equilibrium 2 a new transition control strategy using surface roughness 3 a new set of very high-order upwind multilayer compact MLC schemes with spectral-like resolution for hypersonic flow simulations.
