纳米流体强化传热领域的研究进展及存在的问题

摘要

Put forward higher requirements for the efficiency of heat exchanger system under the background of energy-saving and emissionreduction,Nanofluid is the focus of the research on heat transfer enhancement in recent years.However,there are few articles on the general understanding of the nanofluid.In this paper,at first,we study the research-background,concept,classification,advantages and applications of the nanofluid,secondly,we study the preparation method,at last,we summarize the existing problems and challenges in order to promote the research work in the future.%在节能减排这个大背景下,对换热系统的效率提出了更高的要求,纳米流体是近几年强化传热领域研究的重点,然而对于纳米流体总体上集中认识的文章少之又少.从研究背景、概念、分类、优点、用途到制备方法对纳米流体进行了综述,最后总结了纳米流体存在问题及面临的挑战,以期促进今后进一步的研究工作.
