Abstract:

Experimental convective heat transfer distributions on a hemisphere- cylinder configuration were obtained using slug calorimeters and Gardon gages. Wind tunnel tests were conducted at a nominal Mach number of 10 over a free- stream Reynolds number range from 310,000 to 1,040,000 based on the model diameter 5.80 inches. The data were compared with theoretical heat transfer values and data obtained with thin-skin calorimetric wind tunnel models. The slug calorimeter data were highly time dependent due to conduction heat losses consequently, the data did not compare favorably with theoretical predictions. Gardon gage indicated heat transfer was in very good agreement with both theoretical values and data from other sources.
