摘要

本研究创新性地建立了正弦空腔传热模型,并通过实验探索将其应用于磁场激励下的自然对流传热效应。研究了热输入、纳米流体质量浓度、磁密度、磁场布局等变量对传热的影响。结果表明,水平磁场对传热有削弱作用,最多可使努塞尔特数降低 2.57%。双横向垂直交错磁场的效果最好,努塞尔特数最多可增加 5.37%。在垂直磁场下,增加磁场强度会相应增加熵的产生。最大增幅为 9.11%。这将为电子元件热管理领域的腔体设计和磁性纳米流体的应用提供一些指导,也为未来设计更高效的热管理系统提供了可能。

Effect of magnetic field excitation and sinusoidal curved cavity coupling on heat transfer enhancement and entropy generation of nanofluids

This study innovatively developed a sinusoidal cavity heat transfer model and applied it to the natural convection heat transfer effect under magnetic field excitation through experimental exploration. The effects of heat input, mass concentration of nanofluids, magnetic density, magnetic field layout and other variables on heat transfer were studied. The consequence showed that for heat transfer, the horizontal magnetic field has a weakening effect, which can reduce the Nusselt number by 2.57% at most. The double lateral vertical staggered magnetic field has the best effect, and the Nusselt number can be increased by 5.37% at most. Under a vertical magnetic field, increasing the magnetic field strength will increase the corresponding entropy generation. The maximum increase is 9.11%. This will provide some guidance for design of cavity and the application of magnetic nanofluids in the field of thermal management of electronic components and also provides the possibility for designing more efficient thermal management systems in the future.
