Abstract

The problem of assessing the risk of thermal hitting of employees in case of fire at the gas station is considered. The task is to develop a mathematical model that allows quickly determining the dynamics of temperature changes and, on this base, forecasting the risk of thermal injury to workers in work areas. The energy equation to calculate the dynamics of thermal air pollution during burning is used. An aerodynamic model of potential motion (Laplace equation for velocity potential) to calculate the airflow velocity field in building conditions is used.

Numerical integration of the equation for the velocity potential using the Richardson method and the conditional approximation method is carried out. Differential splitting schemes for numerical integration of the energy equation are used.

The computer program is developed on the basis of the constructed numerical model. The results of a computational experiment to determine the risk of thermal injury to workers in a fire at a gas station are presented.
