Abstract

Purpose. To obtain an algebraic equation that allows calculation the dynamics of the volumetric optical density of smoke in a compartment equipped with smoke ventilation.

Methods. Solving the differential equations of the integral fire model and using computational computer models of fire dynamics.

Findings. An algebraic equation is obtained that allows calculating the dynamics of the volumetric optical density of smoke in a compartment equipped with anti-smoke ventilation with comparable accuracy for the field model of fire.

Application field of research. The presented results were obtained to simulate the effects of dangerous fire factors on people and can be used in practical calculations to evaluate the safe evacuation of people from buildings and structures in case of fire.
