MEASUREMENT OF HEAT TRANSFER ON A FLAT PLATE-STEP MODEL AT MACH 14 (TASK 3.4-SHOCK TUNNEL EXPERIMENTS-REST PROJECT)
Abstract
An experimental study of the separation of a hypersonic boundary layer ahead of a step on a flat plate is reported. The measurements were made in a Mach 14 shock tunnel. The flow field is visually observed with a glow probe. Local heat transfer distribution along the flat plate and up the face of the step is reported. The detailed heat transfer distribution shows a local increase in heat transfer associated with the separation shock, a decrease in heat transfer just downstream of the separation point, and a second increase in heat transfer as the step is approached. Directly at the corner between the flat plate and the step, the heat transfer re verses direction and is from the heat gage to the stream. No explanation was found for the corner effect. Preliminary measurements of the local heat transfer distribution across the separation layer with hot wire calorimeter also reported.
