| 中文摘要: |
| 为了更好地了解近年来微通道研究的发展状况，基于微通道两个不同的尺度级别（微米级、纳米级），对国内外相关研究成果进行了综述。通过对比分析发现，学者们对影响微通道流动与换热的因素，如工质侧的工质种类、微通道侧的通道结构、制作材料以及微尺度效应等进行了研究，但有些结论仍存在争议，甚至部分结果之间相互矛盾。在纳米通道的研究中，由于无法进行实验研究，数值模拟方法得到了广泛的应用；并且在大部分研究中主要采用分子动力学方法；在纳米通道内原子势能对换热性能产生了较大影响。 |
| 英文摘要: |
| In order to better understand the recent development status on micro and nanochannels research, the review on the channels at micro and nano levels at home and abroad was performed. Based on the comparative analysis, it could be found that the influential factors such as working fluid type, channel structure, materials and micro scale effect were studied in detail to reveal the flow and heat transfer characteristics. Some conclusions were much debated. In particular, part of them had the contradiction. As for the nanochannels, because of the difficulty in carrying out the experimental studies, the numerical simulation methods were widely adopted. In most of the research, molecular dynamics method was used. In the nanochannels, the atomic potential energy had a great influence on the heat transfer performance. |
