ABSTRACT
Thermal radiation, although considered an important mode of heat transfer in high temperature conditions, is often neglected in fire modeling, mainly due to the complex physics involved. The predictions are evaluated as part of a complete prediction procedure involving the modeling of the simultaneously occurring flow, convection, and radiation phenomena. The results have demonstrated that the effect of thermal radiation is important, even in small fires. Comparison between the two models indicates that the simple six-flux model suffices for small compartment fires, up to 100 kW. Thermal radiation can be an important mode of heat transfer in processes involving high temperatures and for that reason the computational analysis of thermal radiation transfer in enclosure fire modeling is essential. For fire modeling, on the other hand, very few have been undertaken. Utilizing the methods developed for furnace applications is common practice in fire engineering.
