, 2015 实验研究了微重力环境中,不同热流密度时尾流效应对气泡动力学过程的影响。结果表明,微重力下气泡的尾流效应比常重力时更加明显,低热流密度时尾流对气泡动力学行为影响微弱,中高热流密度时尾流影响效果显著。尾流区内液体的水平流动促进了原生气泡间相互碰撞、合并过程,垂直加热面的流动则给气泡施加了向上的曳力,从而降低了气泡生长周期和脱离半径。尾流区内过冷液体的冷却作用使气泡内形成负压,液体从微柱结构内被吸入气泡底部,为其长大提供新鲜液体,避免局部干斑。尾流效应与微柱结构相互作用,能有效促进加热面的气泡合并和脱离过程 ...

, 2006 提出了制冷剂气体水合物在纳米流体中快速生成的设想，并通过HCFC141b气体水合物在纳米铜流体（由质量分数为0．049／6的十二烷基苯磺酸钠-6（SDBS）溶液和名义直径为25nm的纳米铜粒子组成）中的生成实验验证了此设想．实验结果表明：与去离子水中HCFC141b气体水合物的生成过程相比，纳米铜流体中的SDBS是造成HCFC141b气体水合物诱导时间明显缩短的主要原因，而纳米铜粒子对诱导时间的影响不大；纳米铜流体中汹的乳化作用和纳米铜粒子大的比表面积大大促进了HCFC141b在水中的溶解 ...
