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
predicitons 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 acutal situations relevant to
fire growth and smoke propagation, as is demonstrated.
