Mathematical modeling of the fire within the premise equipped by the system of antismoke ventilation

Abstract

Results of mathematical modeling for the fire parameters within a premise are presented with the account of characteristics of the antismoke ventilations system. The effect of the fire loading kind in the premise on the value of the average-volume temperature of the gaseous medium was studied in case of the work of antismoke ventilation. Mathematical model allowing to evaluate dynamics of the fire temperature in the premise equipped with a system of antismoke ventilation was developed. This modeling was shown to considerably simplify the problem of determination for the parameters of emergency ventilation system already at the design stage. It also enables to estimate the efficiency of ventilation systems in the buildings in the fire conditions.
