Abstract
A heat flux measurement method was developed to analyze heat flow on heat radiating surfaces. Thermal resistances made of plastic plates were attached to the surface. The heat flux was obtained by measuring the temperature difference between the radiating surface and thermal resistance surface. The surface temperature was measured using thermography. Unlike conventional heat flux sensors which are made of thermopiles, this method does not require installing wiring. It also enables the multipoint measurement of heat flux. The heat flux measurement method was applied to model evaluation and proved the potential of measuring heat flux distribution.
