In the present study, we perform direct numerical simulations to investigate the spatial
development and basic flow statistics in the supersonic turbulent boundary layers at the free …

In the present study, we investigate the compressibility effects in supersonic and hypersonic
turbulent boundary layers under the influence of wall disturbances by exploiting direct …

In the present study, the response of a hypersonic turbulent boundary layer at an inflow of
Ma∞= 6 and Re∞= 16· 10 6 1/m to a smooth and rough surface along a sharp cone is …

In the present study, the influences of wall disturbances on coherent structures and the
corresponding turbulent transport in supersonic turbulent boundary layers are investigated …

Wall disturbances in high-speed turbulent boundary layers induce large-scale motions in the
outer region even when the Reynolds number is not sufficiently high for their existence in the …

Flight at hypersonic Mach numbers (M≳ 5) is accompanied by a myriad of complex fluid
mechanical and aerothermodynamic phenomena, many of which find, at best, limited …

This research work studies the effects of surface roughness on shock-wave/boundary-layer
interactions (SWBLIs). SWBLI are prevalent in supersonic and hypersonic flows and occur …

Two-component particle image velocimetry was employed to measure the influence of
surface roughness on a Mach 2 boundary layer. Three surface conditions were examined: a …
