超越麦克斯韦极限:具有渗流流体结构的纳米流体的热传导

Beyond the Maxwell Limit: Thermal Conduction in Nanofluids with Percolating Fluid Structures

Jacob Eapen, Ju Li, Sidney Yip

摘要:

在一个良好分散的纳米流体与强大的集群流体吸引力,热传导路径可以通过蒸发无定形的界面结构出现。这导致超过3*phi的麦克斯韦极限的热导率增强,其中phi是纳米颗粒体积分数。我们的研究结果从非平衡分子动力学模拟,这是经得起实验验证,可以为未来的纳米流体的发展提供了理论基础。

英文摘要:

In a well-dispersed nanofluid with strong cluster-fluid attraction, thermal conduction paths can arise through percolating amorphous-like interfacial structures. This results in a thermal conductivity enhancement beyond the Maxwell limit of 3*phi, with phi being the nanoparticle volume fraction. Our findings from non-equilibrium molecular dynamics simulations, which are amenable to experimental verification, can provide a theoretical basis for the development of future nanofluids.
