FRACTAL GEOMETRY THEORY AND RESEARCH STATUS IN HEAT TANSFER

Fractal geometry theory and the development process and direction are the target of this paper.Abrief introduction of fractal geometry theory is put forwarded.The important characteristics and history of fractal geometry theory are reported.Porous media，honeycomb structure，fractal tree structure are taken as the standard of classification of the summary.And the paper introduces the research status at home and abroad in the filed of heat transfer with the important theories or experimental studies in recent years.Based on the research status，research directions in the future are regarded that improving the fractal theory in heat transfer will increase the efficiency of the heat transfer，reduce the resistance loss，improve the efficiency of the equipment and reduce the cost.
