Separation control using air-jet vortex generators in a hypersonic shock-induced boundary-layer separation
DP Ramaswamy, A Barklage, AM Schreyer - 2020 - publikationen.dglr.de
An experimental analysis was carried out to assess the flow organisation and control
effectiveness of an array of air-jet vortex generators (AJVGs) on an axisymmetric 33 flare
induced shock-wave/boundary layer interaction at Mach 5.15. This is the first study of AJVGs
in a hypersonic shock-wave/boundary layer interaction. Flow configurations for three
different Reynolds numbers and various momentum-flux ratios (J) were investigated using
schlieren and surface oil-flow visualisations. The jets have a diameter of 1mm and are …
