Development of the heat flux instrument using the black body of porous media

The measured accuracy of a heat flux instrument was developed by using the black body of porous media. The SUS 304 stainless wire mesh having PPI (Pores per inch) of 100 and thickness of 0.202 mm constructed by 2 wire-mesh screens was used as the porous media. Three models of a black body of porous...

As heat sources, four 150 W infrared lamps were used and vertically placed on the instrument’s top. Five levels of electrical voltages (E), including 50, 100, 150, 200, and 250 V, were tested.
