Fundamentals of Enclosure Fire Zone Models

There are two main methods in fire modellnig: zone models and field models. The conservation of mass and energy in enclosure is the theoretical base of zone models. The models deal with heat release rate, fire plume, mass flow, smoke movement and gas temperature in fires. Theoretical principles of compartment fire zone modeling are presented and the behavior of fire in enclosures is discussed.The conservation laws are presented in control volume form and applied to the behavior of fire in enclosures. The governing equations are derived and presented. Some zone models and their field of application in fire modeling are also given.
