Conical similarity of shock/boundary-layer interactions generated byswept and unswept fins

摘要: A parametric experimental investigation has been made of the class three-dimensional shock wave/turbulent boundary layer interactions generated by swept and unswept leading-edge fins. The fin sweepback angles were 0-65 deg at 5, 9, 15 attack. Two equilibrium two-dimensional turbulent layers with a freestream Mach number 2.95 Reynolds 6.3 x 10 to 7th/m used as incoming flow conditions. All resulting found possess conical symmetry surface patterns pressures outside an initial inception zone. Further, these obey simple similarity rule based on inviscid wave strength, irrespective or angle This is one first demonstrations among produced geometrically dissimilar generators.
