A. Hamed et al., SHOCK-WAVE BOUNDARY-LAYER INTERACTIONS WITH BLEED .2. EFFECT OF SLOT LOCATION, Journal of propulsion and power, 11(6), 1995, pp. 1236-1241
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.
