Abstract
Thermal conductivity, thermal diffusivity and heat capacity per unit volume of consolidated porous rocks have been studied as a function of temperature with air as a saturant, at atmospheric pressure. The transient plane source (TPS) technique is used for the simultaneous measurement of these parameters. An empirical formulation is shown to account for the computation of thermal conductivity of porous rocks in terms of porosity and thermal conductivities of mineral constituents. The measurements showed a linear increase in thermal conductivity with temperature.
