Abstract:
Relying on the laws of the mechanics of multiphase reacting media, we construct a mathematical model of the ignition of forests by radiation emitted as a result of the explosion of the Tungusskii meteorite. The forest canopy is modelled by a multiphase porous reacting medium. The ignition regimes realized at different distances from the center of the explosion are analyzed. It has been established that the maximum radius of the ignition zone is 6–9 km for the forest canopy and 12–16 km for the ground cover, depending on the stock and moisture content of combustible forest materials. This corresponds to an explosion energy of 25⋅1016 J.
