中文摘要
To measure heat flux on the sharp leading edge and other surface with very small curvature radius in the wind tunnel, Hong-Ru Yu proposed a novel design of integral type heat flux sensor. Compared with the traditional heat flux sensor, the integral type heat flux sensor improved spatial resolution up to an order of magnitude, and the size of the sensing elements has been minimized to 0.1 mm successfully, which satisfied the heat flux measurement requirements at R0.5 mm pointed cone stagnation point. A constantan film was used as the contact layer of the integral heat flux sensor, which was prepared by electron beam co-evaporation method. The influence of sensor structure on the accuracy of measurement was analyzed using numerical calculation. The measurement results in shock wave wind tunnel indicated that the response frequency was about 100 kHz and the repeatability error was less than 10 %.
