Abstract: | Mathematical model of forest fire was based on an analysis of known experimental data and usingconcept and methods from reactive media mechanics. The paper suggested in the context of the generalmathematical model of forest fires gives a new mathematical setting and method of numerical solution of thisproblem. It is based on numerical solution of two dimensional Reynolds equations for the description of turbulentflow taking into account for diffusion equations chemical components and equations of energy conservation forgaseous and condensed phases. To obtain discrete analogies a method of finite volume was used. Dependence ofthe rate of crown forest fire on various characteristics of forest and meteorological conditions is obtained in thispaper. Mathematical model and the result of the calculation give an opportunity to consider forest fire spread fordifferent wind velocity, canopy bulk densities and moisture forest fuel. The results obtained by the model are compared to experimental measurements and data of others authors. |
