Effect of water saturation and temperature in the range of 193 to 373K on the thermal conductivity of sandstone

The thermal conductivity of porous media is crucial for many geological and engineering projects. Although the thermal conductivity at low temperatures is often overlooked, it is of great significance to calculate the amount of heat that the ice sheet absorbs from the Earth. In this study, the thermal conductivity of dry and water-saturated sandstone was measured in the temperature range of 193 to 373 K using a transient hot wire method. All...
