| Abstract: | A temperature sensitive paint (TSP) technique is developed for the request of boundary layer transition measurement, and a test of hypersonic boundary layer measurement of a flat plate is done in CARDC 0.6m shock tunnel. By use of the TSP technique, the measurement of the hypersonic boundary layer transition of slab has been done in the shock tunnel. The test nominal Mach numbers are 8 and 10, the unit Reynolds numbers are 2.45×10 7/m and 4.48× 10 6/m respectively, and the yaw angle is 20°. The data of heat transfer and transition position obtained by the TSP and measurement results of the thin film heat transfer sensor match well. The results illustrate that the TSP technique has the ability to measure the hypersonic boundary layer transition of simple model qualitatively and quantitatively in shock tunnel. |
