EFFECTS OF MACH NUMBER ON UPSTREAM INFLUENCE SCALING IN SHARP FIN-INDUCED SHOCK WAVE TURBULENT BOUNDARY AYER INTERACTIONS

摘要

A parametric experimental study has been made for shock wave/boundary layer interactions induced by a sharp fin. The tests were carried out at M=1.75, 2.0 and 2.5, and Re=2.4 x 10~7/m. The results show that the upstream influence depends not only on the inviscid shock strength, but also on the cross flow and the flow separation. A simple scaling correlation including freestream Mach number effects was deducted from the present study.
