摘要：

The variation of capillary pressure with saturation reflects the internal structure of wet unsaturated porous media and the probable contribution of solid, liquid, and gas phase. A model is proposed which effectively predict the thermal conductivity of both saturated and wet unsaturated unconsolidated porous media. The comparisons with the experimental data for saturated porous media show that the present model is reasonable and feasible to predict the thermal conductivity of porous media.
