“…The gas blowing/suction through a perforated (porous) surface is widely used in various tasks of aeronautical engineering (e. g., walls cooling, boundary layer control, separated flows, etc.). The major theoretical and experimental investigations of using blowing/suction through the perforated surfaces in the gas dynamic problems were performed for subsonic speeds [1,2]. The number of experimental studies in the field of using blowing/suction through the perforated surfaces for supersonic flows is essentially lower.…”

In this paper a numerical and experimental study of the effect of blowing/suction through a perforated surface on a turbulent boundary layer at a Mach number M=1.4 was carried out. Most of the calculations were performed by Reynolds-averaged Navier-Stokes equations with the kappa-ω SST turbulence model. The calculated geometry completely repeated the experimental one including the perforated surface. The numerical data were compared with experimental measurements obtained by the PIV method. Analysis of the data made it possible to find the limits of applicability of the numerical method for the flow under study. Keywords: supersonic flow, gas blowing/suction through a perforated surface, boundary layer, turbulence model kappa-ω SST, PIV method.
