Изучение механизма распространения низового лесного пожара с помощью численного эксперимента

Abstract

One of the models of the ground forest fire, which is of great practical importance, is the model of the spread of a ground fire through a layer of forest combustible material. When assessing fire hazard, the properties of forest combustible materials, meteorological conditions are taken into account. The speed of the wind and the moisture content of the forest combustible material are of decisive importance for the assessment and analysis of the existing situation, and also for forecasting. To obtain an adequate mathematical model and a successful formulation of a numerical experiment, a full and correctly described physical model of a forest fire plays a decisive role, taking into account those of its mechanisms that play a decisive role.
