摘要
纳米颗粒种类、粒径、基液性质、分散剂种类和用量、pH值和超声振动等因素对纳米流体的悬浮稳定性都有不同程度的影响,并且它们不是单独发挥作用,而是存在着一定的联系和相互作用。本文综述纳米流体悬浮液稳定性最新研究进展,系统分析其作用机理,总结了几种常见纳米流体处于最佳稳定效果时各影响因素的取值,并展望了纳米流体应用于水合物蓄冷材料的应用前景。
Nanofluid is a new kind of heat transfer enhancement fluid.Nanofluid＇s suspension stability is influenced by some factors which include nanoparticles,basefluid,dispersant type,dispersant dosage,pH value and ultrasonic vibration.There are some connections and mutual effection between these factors.The recent researches of factors of nanofluid＇s suspension stability and their function mechanisms were summarized.The value of these factors when nanofluid is in the best stable state are also provided.
