Simulation of large-scale forest fire parameters

Topicality. There is an urgent need to select the main energy, geometric and thermophysical parameters of forest fires, as well assess these including unexplored fire tornadoes wave processes caused by fires. Purpose. To develop mathematical models physical large-scale evaluate Methods. Analytical review research problem, theoretical computational, modeling, systematic analysis set effects. Results. The results fires related are presented. proposed. These include: power, duration, area length, intensity speed combustion front, heat flux density, power torch height, smoke rise convection speed, etc. Simple analytical have been created. A model a fiery tornado obtained ratios allow us estimate that accompany include radius, angular velocity, tangential maximum height rate heated formation. It shown that, depending on size vortex, vary widely. relationships make it possible analyze generated Such relative share range periods acoustic radiation, calculated. fire, Conclusions. Mathematical developed, means which effects
