The Effective Thermal Conductivity of Unsaturated Porous Media Deduced by Pore-Scale SPH Simulation

The smoothed particle hydrodynamics (SPH) method was employed to simulate the heat transfer process in porous media at pore scale. effective thermal conductivity of a medium can be predicted through simulation experiment SPH. accuracy SPH verified by comparing values with reference for ideal homogeneous and multiphase layered media. 3D experiments were implemented granular generated PFC method. Based on framework, concise proposed produce unsaturated simulating wetting dry This approach approximates formation liquid bridges water films granules. Through experiments, empirical formula variation degree saturation tested. results showed that reciprocal normalized are linearly related, which is line Cote Konrad.
