摘要
文中综述了目前国内外对于纳米流体强化传热技术的研究情况,分析了纳米流体的强化传热机理及添加纳米粒子后对液体的物性参数——粘度、比热、密度、流体流动的影响;说明了石墨/水纳米流体及Fe3O4/水纳米流体导热系数和对流换热系数测量实验的原理及结果,并对结果进行了分析,实验结果表明纳米流体强化了传热。
This paper generalized the achievements of domestic and abroad investigation about heat transfer enhancement of nanofluids.The heat transfer enhancement mechanism of nanofluids was analyzed from the physical properties and flowing conditions.The main influencing factors of nanofluids were particularly described.The thermal conductivity and the convective heat transfer coefficient of Graphite/water nanofluids and Fe3O4/water nanofluids are also discussed.
