Mathematical Modelling of Distribution Local Forest Fire on the Fallen Down Needles with Fire-Prevention Breaks
The mathematical model describing processes of ignition and distribution of a wave of burning on a porous layer of wood combustible materials, havingfire-prevention breaks is considered. Processes of an exchange by heat and the weight, proceeding in a torch of a flame and its interaction with a burning layer pay off on empirical dependences. It is shown, that the offered mathematical model with good accuracy models distribution of a wave of burning on a dense layer of wood combustible materials (thefallen down needles, a laying, etc.), allows to count the sizes of fire-prevention breaks. Dependences of length of a torch and width of fire-prevention break from a stock of a combustible material, moisture content and conditions of an exchange by heat and weight of a wood combustible material with a ground layer of air are received.
