Abstract

In order to study the influencing factors of heat transport characteristics in the rough fractured dual porous media, the theoretical model of effective thermal conductivity (TC) in rough fractured dual porous media is established in this paper. By calculating the thermal resistance and TC of rough cracks, it is found that the heat transport capacity of the fracture is inversely proportional to the relative roughness and porosity and is proportional to the solid-liquid TC ratio and the fractal dimension of the fracture. The heat conduction in the fractured dual porous media is mainly controlled by the matrix. In addition, by comparing with other models and existing experimental data, it can be seen that the heat transfer capacity of dual media is stronger than that of single porous media. The predicted TC of rough cracks is lower than the experimental data, which is in line with the actual situation, and the model is reasonable.
