在这项研究中，我们报告了高温纳米流体比热容的异常增强。在碱金属氯化物盐共晶中掺杂质量浓度为1%的二氧化硅纳米粒子。纳米流体的比热容提高了14.5%。通过扫描电子显微镜（SEM）证实了纳米粒子在共晶中的分散行为。列举了三个独立的竞争运输机制来解释这种异常行为。(C)2010爱思唯尔有限公司保留所有权利。
In this study, we report the anomalous enhancement of specific heat capacity of high-temperature nano-fluids. Alkali metal chloride salt eutectics were doped with silica nanoparticles at 1% mass concentration. The specific heat capacity of the nanofluid was enhanced by 14.5%. Dispersion behavior of the nanoparticles in the eutectic was confirmed by scanning electron microscopy (SEM). Three independent competing transport mechanisms are enumerated to explain this anomalous behavior. (C) 2010 Elsevier Ltd. All rights reserved.
