The Numerical Implementation of the Method for Determining the Thermal Impact of Gas Blowout Fire, Considering the Wind Direction

Abstract

The article provides a method for calculating the irradiation coefficient of a gas flame, inclined under influence of the wind, an arbitrarily located object in relation to the ground, the distance from the fire and the direction of the wind. The flame is brought to a circular inclined cone. A person was selected as a potential object of risk. The calculation of the irradiance coefficient was made by a numerical method. To check the adequacy of the adopted model, a calculation was made according to the well-known formula for approximating a flame by a vertical cylinder, considering it a particular case of a cone. When comparing the calculation by numerical integration method with calculation by formula, the match of results was found. We also provide directions for further research in this area.
