High Heat Flux Sensors Calibration Using Blackbody Radiation



A V. Murthy, Benjamin K. Tsai, Robert D. Saunders


This paper deals with the radiative calibration aspects of high heat flux sensors using blackbody radiation. Several heat flux sensors were calibrated up to 50kW/m2 in the last two years using a 25 - mm diameter aperture variable temperature blackbody and a reference room temperature electrical substitution radiometer. Tests carried out on a typical Schmidt-Boelter heat flux sensor showed long term repeatability of calibration within -0.6%. Plans for extending the present calibration capability to 100 kW/m2 are discussed.
