摘要
本文论述了分形介质的分形理论和数学基础,并简要综述了用分形理论和方法研究分形介质的传热与传质特性(如多孔介质的渗透率、热导率以及池核态沸腾换热)方面目前所取得的研究进展,最后扼要展望了用分形理论和方法进一步研究分形介质的传热与传质的可能的若干课题和方向。
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.
