Abstract: | An analysis has been carried out to investigate the effect of the reflectivity on the temperature distribution of a glass
panel by infrared radiant heating. Halogen lamps are used to heat the panel, located near the top and bottom of the rectangular
chamber. The thermal energy is transferred from the lamps to the panel only by radiation and it is considered by using view
factor. The conductive transfer is limited inside the panel. The results show that the uniformity of the temperature distribution
of the panel is improved and, at the same time, the time for heating increases as the wall reflectivity increases. The temperature
difference between the center and the corner reaches a maximum in the early stage of the heating process and then decreases
until it reaches a uniform steady-state value. |
