In fields such as construction, insulation, packing, heating, chemical and oil industries, the thermal conductivity of porous granular beds plays vital roles in process design, optimization and implementation. In in-situ thermal oil recovery processes, for instance, effective thermal conductivity data for a particular reservoir matrix is an essential parameter for the effective simulation of the thermal process, whether analytical or physical. The effective thermal conductivity of dry and water wet sands and granular matrices of glass beads was established experimentally. Different values of practical and experimental combinations of grain size, porosity, water saturation and temperature were considered, under atmospheric pressure conditions. The effective thermal conductivity values for such multiphase porous systems were then correlated successfully in terms of the thermophysical properties of the individual components involved and their relative composition.
