Abstract:This paper presents an overview of the recent advances made in predicting heat and mass transfer in fractal media by fractal theory and technique. The theoretical basis for fractal analysis is addressed, including the analytical expressions for fractal dimensions, a criterion on whether the fractal theory and technique can be applied. Several fractal models are presented and reviewed. These include fractal permeability models, fractal thermal conductivity models for saturated porous media, as well as a fractal model for pool boiling heat transfer. A few comments are made with respect to the theoretical studies that should be made in this area in the future.
Keywords:fractal  fractal media  heat and mass transfer
