Wall heat flux in the hypersonic boundary layer over the windward side of a lifting body
We conduct comprehensive investigations by direct numerical simulations on the wall heat flux (WHF) in the hypersonic boundary layer over the windward side of a lifting body, which is affected by non-canonical effects, such as the wall curvature and pressure gradient. Based on the framework of conditional analysis, the generation mechanism of extreme WHF events is illustrated in two perspectives: identifying the coherent structures and quantitatively characterizing energy transport. We explore quite different features of WHF in the central and side regions of the lifting body.
