Abstract

The mathematical modeling of forest fires actions on buildings and structures have been carried out to study the effects of fire intensity and wind speed on possibility of ignition of buildings. The crown forest fire is modeled using physical two-phase model of forest fire proposed by Grishin. The hydrodynamic and thermal interactions between plume, wind flow and building are analyzed. The non-stationary three-dimensional conservation equations for turbulent flow in a multiphase reacting medium that are solved numerically under the input conditions characteristic of a large forest fire. As a result of numerical calculations, the dependences of the distances from the front of the fire to buildings at which the ignition of the latter are possible are obtained.
