分形理论及其传热研究现状

FRACTAL GEOMETRY THEORY AND RESEARCH STATUS IN HEAT TANSFER

总结了分形理论及其在传热领域的发展过程并探究发展方向。对分形理论进行了简要的介绍,对其重要特征和发展历程予以回顾和展望,以多孔介质、蜂窝结构、分形树杈结构为分类标准,将研究成果进行归纳总结,重点评述其在导热方面的国内外研究现状,以及近些年较为重大的理论或者试验研究成果,并以此为依据提出完善分形理论在传热学领域的应用,能够有效提升换热器换热效率,减少阻力损失,提高设备工作效率并降低成本,是未来的研究和发展方向。

Fractal geometry theory and the development process and direction are the target of this paper.A brief 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.
