Description
Spatial direct numerical simulations are used to study the formation and development of three-dimensional structures in a supersonic flat plate boundary layer, where the free-stream Mach number is three and the Reynolds number at the inlet based on the displacement thickness 1,000. Random disturbances are superimposed on the laminar profile at the inlet plane of the boundary layer computational box. Hairpin vortices are generated in an intermittent manner on a low speed streak downstream after the low/high speed streaks formation. The numerical turbulent velocity fluctuations are in good agreement with the experimental data of the supersonic turbulent boundary layer for M = 2.9.
