Abstract:

This paper describes a model of fire growth and smoke transport for compartmented structures, with emphasis on those aspects which are important to making correct predictions of smoke movement in multicompartment structures. In particular, we are interested in the ability to model the movement of toxic gases from the room of origin of a fire to a distant compartment. The newest phenomena in the model are vertical flow and mechanical ventilation. Finally, we have improved the radiation transport scheme which affects energy distribution, and therefore the buoyancy forces. These are very important in a actual situations relevant to fire growth and smoke propagation, as is demonstrated.
