The hot surface temperature was measured with a 0.5-mm-diameter wire K type, inconel shielded, grounded thermocouple fastened to the center of the surface. With the center temperature at 700 C, the edge temperatures were about 50 C lower than the center temperature. In this study, the center temperature was used as the hot surface temperature.
