On the Influence of Boundary Conditions in Modeling Heat Transfer in Soil

A procedure to determine the thermal diffusivity of soils, which is based on the heat-transfer equation, has been developed. Experimental investigations were carried out to establish the influence of boundary conditions on the soil surface on the solution of inverse problems of modeling of heat transfer in soil. On the basis of these data, the author has calculated thermal diffusivity in soils with the proposed methods developed for the case with one and two harmonics and a comparison of these methods has been made; the calculated characteristics and experimental results have also been compared. © 2017, Springer Science+Business Media New York
