Three Dimensional Modeling of Radiative Heat Transfer in Furnaces

An industrial furnace could be considered as the 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 dimensional 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 useful numerical method for considering multi-dimensional thermal performance of gas-filled enclosures.
