The study of heat transport characteristics in tree-like bifurcating networks holds significant importance in fields, such as microelectronic cooling, biomedical engineering, and advanced material design. However, most existing models primarily focus on symmetric tree-like bifurcating networks, while studies on asymmetric networks often overlook the effects of conduit tortuosity and fluid unsaturation. This work, grounded in fractal geometry and thermoelectric analogy theory, incorporates the influence of surface roughness to develop a fractal model for the effective thermal conductivity of unsaturated, asymmetric tree-like bifurcating porous media. The study systematically investigates the impact of relative roughness, tortuosity fractal dimension, liquid phase saturation, and structural parameters of asymmetric bifurcating networks on the heat transport process. The theoretical predictions align well with experimental data, validating the accuracy and reliability of the model. Consequently, this research contributes to the advancement of heat transport theory in asymmetric tree-like bifurcating porous media and provides theoretical guidance for material design and related applications.
