Thermophysical properties of consolidated porous rocks

Thermal conductivity, thermal diffusivity and heat capacity per unit volume of consolidated porous rocks have been studied as a function of temperatur e with air as a saturant, at atmospheric pressure. The transient plane sour ce (TPS) technique is used for the simultaneous measurement of these parame ters. An empirical formulation is shown to account for the computation of t hermal conductivity of porous rocks in terms of porosity and thermal conduc tivities of mineral constituents. The measurements showed a Linear increase in thermal conductivity with temperature.
