ABSTRACT
The ability to numerically estimate how much heat is transferred between a fire, the fire gases, the fuel bed, and the surfaces in an enclosure is essential for any fire hazard assessment. The energy balance is very much affected by heat being transferred from the flames and the hot gases to the enclosure surfaces and out through the enclosure openings. The heat transferred from these sources toward a fuel package will to a considerable extent control the rate at which fuel evaporates and heat is released. This chapter briefly discusses convection heat transfer as applied to enclosure fires, but most of the text is dedicated to radiative heat transfer in enclosures. It is presumed that the student already has a background in the fundamentals of heat transfer.
