HEAT-TRANSFER AND PRESSURE INVESTIGATION OF A FIN-PLATE INTERFERENCE MODEL AT A MACH NUMBER OF 6

摘要

A 60° swept cylindrical-leading-edge fin mounted on a sharp flat plate was investigated at a Mach number of 6 over a range of Reynolds numbers, based on free-stream conditions and fin leading-edge diameter, from 0.062 x 10° to 0.77 X 106 . The plate was maintained at zero angle of attack and the yaw angle of the fin was varied from 0° to 30°. A relatively weak shock wave which orig¬inated at the leading edge of the plate impinged on the leading edge of the fin. Heat-transfer rates and pressures were measured on both the plate and the fin. The measured data on the fin and plate are compared with values calculated from laminar and turbulent theories for an infinitely long 60° swept cylinder and undisturbed plate.
