Keywords:modeling, visibility, smoke generating ability, specific smoke output, visibility factor, specific extinction index, illumination, reflection coefficient
Purpose. The development of a methodology for calculating visibility at a fire, based on a mathematical model of the propagation of optical radiation through a scattering medium and supplemented by taking into account modeling parameters.
Methods. Simulation of smoke dynamics in a fire.
Findings. A method for calculating the visibility of a fire based on a mathematical model of the propagation of optical radiation through a scattering medium and supplemented by taking into account the color of the interior of the premises, comprehensive assessment of the smoke-generating ability of the fire load and its share of combustion is presented. A methodology for determining the values and application of parameters for modeling visibility at a fire is described.
Application field of research. The results can be applied in fire modeling.
