主　　题：CONTROL OF STRONG SHOCK TURBULENT BOUNDARY LAYER INTERACTION IN RECTANGULAR CHANNELS 

摘      要：Under initial conditions of Ma= 1.63 and δ= 5.65mm, the controlling techniquesof strong shock-turbulent boundary layer interactions in rectangular channels are investigatedsystematically in this paper. It is found that for an effective improvement on boundarylayer parameters and reducing the turbulence level of flow downstream ofshock-boundary layer interaction, the bleed mass flow G = 2～2.5%, and the width of suctionslot W/δ= 0.88 and its position of L / δ= 1.77 are the most suitable values amongthe G, W /δ, L/ δand B studied. Experiments reveal that for improving the steadyand dynamic characteristics of flow in the channels it is necessary for channels with highvalue of Bto control effectively the strong shock-boundary layer interaction.
