title: Development of integrated high temperature sensor for simultaneous measurement of wall heat flux and temperature.
abstract: In this paper, an integrated water-cooled sensor has been developed to simultaneously measure the heat flux and temperature at the wall of a scramjet combustor. The upgrade sensor was designed based on the principle of Gardon heat-flux gauge with many improvements. The sensor was well calibrated by both conductive heating sources and blackbody cavity device. The effects of structural material and dimensions on the sensor's responses were examined. Both the experimental measurements and numerical simulation were conducted and showed that the new sensor has the maximum measure ability of heat flux of 400 W/cm(2) and stagnation temperatures up to 1920 K along with satisfactory response time.
