Mathematical Modeling of Heat and Mass Transfer in Fire in a Compartment of Complex Geometry
RÉSUMÉ
A mathematical model is suggested for calculation of heat and mass transfer in fire in a compartment of complex geometry. Comparison with experimental data is given. Results of calculations of three-dimensional temperature fields in a gas medium of the compartment and within enclosing structures, velocities and vision range in the case of simulated fires in compartments of complex geometry: atrium, corridors, and stories of the buildings, as well as in the area under the balustrade of the metropolitan railway escalator, are presented. It has been found that in all analyzed cases the impact of the compartment complex geometry gives results that are unexpected in terms of integral and zonal fire models. It has been shown that the proposed computational method allows one to identify the regularities of heat and mass transfer that substantially modify modern concepts about the dynamics of hazardous factors of fire in the analyzed compartments.
