Abstract

Forest fires have an adverse effect on soils. The so-called pyrogenic soils can be formed. In this paper, we have modeled mathematically unsteady conductive heat transfer in soil under the action of a local ignition source. Physical and mathematical models of heat transfer in the layer structure of soil have been developed. Temperature fields at different instants of time, the one-dimensional temperature distribution over the soil cross section, and also the dependence of the temperature on time at a characteristic point of the soil have been obtained as a result of numerical investigation. Further advance of the present scientific line can provide a fundamental basis for development of information and computation systems of environmental monitoring of soils during fire-hazardous seasons.
