JOINT INFLUENCE OF HIGH ENTROPY LAYER AND GOERTLER VORTICES ON HEAT TRANSFER IN SUPERSONIC COMPRESSION RAMP FLOW
要約
The joint influence of a small bluntness-generated high entropy layer and Goertler vortices is investigated numerically for a laminar supersonic compression ramp flow at free stream Mach number M∞ = 8 and Reynolds number ReL ~ 3.71 × 105 based on flat plate length. Beside the fact that Goertler vortices result in spanwise variation of the heat flux coefficient with respect to its average level, they are also found to increase the average level. The high entropy layer is shown to dramatically reduce heat flux and its spanwise variations due to vortices in the reattachment region, with Goertler vortices suppressed.
