Transient Heat Transfer Measurements on a Film Cooled Flat Plate in a Shock Tube

Abstract

During this study a simple model of a flat plate was chosen to determine heat flux from a high speed flow behind a shock wave into the film cooled flat plate. An electrical analog was used to convert the output of the heat flux gages into heat flux. Free stream turbulence within the flow behind the shock wave and that generated by a turbulence generator was determined and its effects on the heat transfer data were then studied for comparison with previous experimental work. The thin-film heat flux gages were calibrated and their calibration constants were then used to determine the true heat flux into the flat plate. Film cooling flows were studied under three different primary flow conditions. Cool air was injected into the boundary layer on the flat plate, and analyzed for its effects on the heat transfer to the flat plate.
