MATHEMATICAL MODEL OF CROWN WILDFIRE INITIATION IN THREE-DIMENSIONAL SETTING

Abstract

The results of calculations of the initiation of crown wildfire under influence of surface wildfire, derived from a general mathematical model of fire are presented. A computer program for calculating the ignition of crown wildfire in time for different meteorological conditions (wind speed, ambient temperature, etc.) and characteristics of forests (moisture and the bulk of forest fuel materials, trees and their height, etc.) was developed. The computer program is used for the calculation of critical condition of the possibility of crown wildfire initiation.
