عنوان مقاله [English]
An industrial furnace could be considered as a three dimensional enclosure. The zonal analysis of radiative heat transfer modeling is used for finding the three dimensional temperature distributions. Exchange areas are determined by simplified numerical integration in three dimension for surface-surface, surface-gas, and gas-gas zones for absorbing and emitting media. The effects of some important parameters in the furnaces are described. It is shown that the zonal method is a useful numerical method for considering multi-dimensional thermal performance of gas-filled enclosures.
