The influence of anontotal reflection on the interaction of areflected shock wave withthe boundary layer in a refleeted Shock lunnel has been investigated The calculatingmethod of the velocity,the tempeture and the Mbch number profiles in the boundary layerin reflected shock fixed coordinates has been obtained To account for equilibrium real gaseffects of nitrogen the numerical results show that the minimum Mach number in theboundary layer has been movedfrom the wall into the boundary layer with the increasing ofthe incident shock Mach number.The minimum Mach number,the shock angle in thebifurcated foot and the jet velocity along the wall to the end plate are reduced owing to theincreasing of the area of nozzle throat.The numerical resulls are in good agreement withmeasurements.
