微通道气液两相流研究进展
Research progress of gas-liquid two-phase flow in micro-channels
摘要
Abstract
Detailed description of the background and application of the micro-chemicals, Bubble characteristics and mass transfer in micro-channels are also reviewed.Introduce the gas-liquid two-phase flow pattern,formation process and influencing factors of it in micro-channels (horizontal and vertical micro-channels).Focus on the introduction of the bubble formation and empirical formula of bubbles length.Compared the relationship between gas-liquid flow ratio and the bubble length in empirical formula of various researches.The results show that the bubble length increases with the increase of velocity gas-liquid flow ratio,but the increasing trend is not the same according to the experimental conditions of the researchers.For mass transfer,the study basically focused on the bubble flow and the annular flow which have larger specific surface area.Although gas-liquid two-phase flow in micro-channels has a great application prospects in the heat transfer,mass transfer.there are still some problems like research method singleness and theoretical data is not perfect.It is pointed out that in the future research, the researchers should expand the scope of the field and provide a more reliable theoretical basis for the practical application of mass transfer.关键词
