As a transport property, effective thermal conductivity of porous media has received much
attention due to its wide applications in many fields, including chemical engineering, soil
science, engineering, oil production, polymer composite molding, etc. The microstructures of
porous media are usually disordered and extremely complicated in nature, which makes it
very difficult to obtain an analytical expression for the thermal conductivity, especially for the
natural unsaturated or multiphase porous media. In the past, the thermal conductivity of …
