| 摘 要： | 气／液两相流流型是两相流研究领域最基本的课题之一，至今已有数十年的研究历史．但是，由于气／液两相流动现象极为复杂，目前还没有得到一致的结论．近十多年来，利用微重力环境减弱甚至完全消除重力的影响，简化流动中各种不同因素间的相互作用及流型特征，大大促进了对气／液两相流动特征及流型产生与转换机理的研究．同时，微重力条件下的气／液两相流动是空间技术领域必须解决的关键技术问题之一，具有重要的学术意义和重大的应用价值．本文简要总结了微重力条件下气／液两相流流型研究的基本方法以及实验结果和理论进展，指出今后研究中应该注意的一些方向．

| Abstract: | Two-phase gas-liquid flow is important for both scientific research and engineering application. The study of flow pattern is one of the most basic topics in this area. It is, however, an unfortunate fact that there isn't a generally recognized theory for flow pattern transition prediction because of its complexity at normal gravity. In microgratvity environment due to the absence of gralvity the dynamical interaction between different factors in the flow will be simplified and then flow patterns will become much simpler than those in normal gravity. It is thus very beneficial to study the mechanism of flow pattern transitions. A review of available literature pertaining to gas/vapor-liquid two-phase flow under microgravity conditions is presented, including the basic approaches and the results of testing and modeling. Some trends for future research in microgravity are also pointed out. |
