Abstract
Heat transfer of ground which is assumed as a composition of soil grain and water is affected by various thermal properties of the materials. It seems that in case of real permeable grounds heat transfer by convection also should be considered in addition to the heat transfer by conduction. This paper describes FEM analyses in which the effects of conduction as well as convection are taken into account in heat transfer phenomenon. Then numerical results of parametric analysis concering the variation of different material properties likes porosity, specific heat, and thermal conductivity are discussed. Finally, presented analytical method is applied to the ground with linear heat source and a crack filled with water.
