Nanofluids are considered to be a next-generation heat transfer medium due to their excellent thermal performance. To investigate the effect of electric fields and magnetic fields on heat transfer of nanofluids, this paper analyzes the mechanism of thermal conductivity enhancement of nanofluids, the chaotic convection and the heat transfer enhancement of nanofluids in the presence of an applied electric field or magnetic field through the method of literature review. The studies we searched showed that applied electric field and magnetic field can significantly affect the heat transfer performance of nanofluids, although there are still many different opinions about the effect and mechanism of heat transfer. In a word, this review is supposed to be useful for the researchers who want to understand the research state of heat transfer of nanofluids.
由于其优异的热性能，纳米流体被认为是一种下一代传热介质。为了研究电场和磁场对纳米流体传热的影响，本文通过文献综述的方法，分析了纳米流体热导率增强的机理、混沌对流以及在施加电场或磁场的情况下纳米流体的传热增强情况。我们检索的研究表明，尽管关于传热的影响和机理仍存在许多不同观点，但施加电场和磁场会显著影响纳米流体的传热性能。总之，这篇综述对于想要了解纳米流体传热研究现状的研究人员应该是有用的。
