Abstract
Calibration methodology of heat flux sensors for measurement of high-density heat fluxes is suggested. The choice of reference emitter is substantiated and construction of Gardon’s heat flux sensor is described. The difference of suggested heat flux sensor is that it realize indirect measurement of heat flux density, which is based on registration of heating speed of cylinder with high heat capacity and of intensity of heat exchange with its sheath. Three cases of heat flux meter calibration methodology are described: calibration with help of black body model and assistive body with high heat capacity; with help of Stefan-Boltzmann law and black body model; with help of high intensive lamp and assistive body with high heat capacity. Experimental facilitate is suggested and it’s construction is described. Article presents also the results of experimental investigation for each case of calibration methodology. Presented calibration characteristics shows good accordance at wide range of temperatures and heat flux density.
