纳米流体制备技术与组成结构的研究进展

摘要

Nanofluids as new working fluids have been highly concerned by the scientists.The instability of nanofluids is a tech-nical bottleneck that hinders its wide application.In view of this problem,many important research achievements have been ob-tained.The nanofluids preparation technology and structure of the latest research progresses in methods of preparing nanofluids, dispersion methods of nanofluids,suspension stability of nanofluids and aggregation structure of nanofluids are reviewed and dis-cussed.Finally,major areas of future research for preparing nanofluids with high suspension stability are proposed in this work.%纳米流体作为一种新型换热工质日益受到科研及工程技术人员的高度关注，但纳米流体的不稳定性是阻碍其广泛应用的技术瓶颈。针对这一问题，目前已经取得了许多重要的研究成果。本文从纳米流体的制备方法、纳米流体的分散措施、纳米流体悬浮稳定性分析、纳米流体的聚集结构等几个方面对当前纳米流体的制备技术与组成结构的国内外最新研究成果进行了介绍，并从制备高稳定性纳米流体的目标提出了对今后研究重点的建议。
