SHOCK-WAVE BOUNDARY-LAYER INTERACTIONS WITH BLEED .2. EFFECT OF SLOT LOCATION

The effect of bleed configuration in the interaction region of an obli que shock wave and a turbulent boundary layer was investigated using n umerical simulations. The numerical solutions to the compressible Navi er-Stokes equations reveal the Bow details throughout the interaction zone and inside the slanted and normal bleed slots. Different bleed ma ss flow rates up to 16% of the incoming boundary layer are obtained by changing the plenum pressure, Results are presented for an incident o blique shock of sufficient strength to cause boundary-layer separation in the absence of bleed. The results show the flow characteristics in cluding an expansion/compression wave system across the slot opening a nd recirculation zone inside the slot. The performance of the differen t bleed configurations is compared in terms of the discharge coefficie nt and the boundary-layer characteristics downstream of the interactio n, at the different bleed mass flow rates.
