摘　　要：自从纳米流体的概念提出以来,因为纳米颗粒添加到基流体的优点,相关的研究蓬勃发展。加入纳米颗粒将改变基液的流变性能,进一步提高传热流体的热性能,为我们提供了广阔的应用前景。然而,纳米流体传热机制的基准理论尚未成熟,纳米流体的研究工作还存在许多矛盾和争议。例如,如果将纳米颗粒添加到基液中,是否会增强或恶化传热流体的对流和沸腾传热性能。综述了纳米流体的热物理性质、对流和沸腾传热性能的最新进展,为纳米流体研究的各个方面提供了研究资源,并确定了纳米流体热性能研究的未来工作。Since the definition of ＇ Nanofluid＇ has been introduced, research related to it has developed and emerged in an endless stream for the advantages of nanoparticles added to the base liquid. The ability of added nanoparticles to tune the heat transfer and rheological properties of the used base liquid would bring us amount of promising applications. However, the basic theory of mechanism of heat tranfer for nanofluid was not well standardrized, and there were still many inconsistencies behind the mechanisms of thermal conductance increase of nanofluids and whether enhancement or deterioration in convective and boiling heat transfer performance of nanofluids. Recent developments are reviewed of transport properties like thermal conductivity and viscosity of nanofluids and nanofluids heat transfer performance under both convective and boiling conditions in order to provide researchers resources about different important aspects of nanofluids, and identify potentials for future study.
