| 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. |
