Smoke filling model for closed compartment

Abstract

Smoke filling problem for fully closed compartment is considered within the framework of the zone modelling approach. Fully analytical solution for the developed model is obtained. It is demonstrated that temperature of the
bottom layer necessarily increases, which is a major difference from the conventional smoke filling process in compartments with openings where the bottom layer remains at the ambient temperature throughout the process.
Analytical solution is compared to Computational Fluid Dynamics (CFD) simulations, and good agreement is demonstrated. Potential practical applications of the developed model are discussed. These include estimation of fire hazards in clean rooms, as well as prediction fire development in storages of some bio- and chemically active materials.
