Experimental Investigation of the Regimes of Thermal Action on a Layer of Soil Exposed to Inert Heating

Research output: Contribution to journalArticlepeer-review

Abstract

A typical porous material enriched with organic matter, soil, is considered. Investigation of the thermal regimes of such materials exposed to a high-temperature action is important for solving ecological and environmental protection problems, and also those of agriculture. Many authors have established that thermal action on the near-surface soil can have a negative effect on both the soil itself, and further development of grass and forest stands. There is a need for the development of a system of geomonitoring accounting for thermophysical processes in the soil at the level of mathematical models. Verification of such models requires the conduct of experiments. In this investigation, we propose an experimental setup for physical simulation of heat transfer processes in a layer of typical soil exposed to high temperature whose source is an inert heater. A set of thermocouples is set up in the soil layer at different depths. Typical curves are presented demonstrating time dependences at different depths of the layer, as are the results of the analysis of temperature dependences.
