Basic mechanisms of heat transfer in granular media have been presented in this paper. The erfective thermal conductivity calculated for different models of the granular structure was formulated as a multivariable function, where the effect of varloua factors had been taken into account, e.g. type of grain space configuration, pressure of fluid filling the pores, thermal conductivities of individual components of the medium, grain, diameter and its surface roughness, porosity, moisture contents, impact of the external mechanical load etc. In this review various formulas recorded in the available literature have been classified with the account to the effect of the particular thermodynamic, structural and mechanical interactions.
