| 摘 要： | 在工业生产过程中，气泡在液相中的上升行为及气液界面的传质行为极为常见。本文针对不同条件下气泡上升过程的实验研究方法以及数值计算方法进行了总结。从实验与数值计算的角度，综述了单气泡上升过程的影响因素、多气泡上升过程聚并与破裂的现象和机理以及工业装置中气液两相流型和气泡特性，并对传质模型进行了归纳，主要关注了气侧-界面传质模型的研究现状。综述结果表明：当前对于单气泡上升行为的研究较为充分，而对于多气泡的行为机理的研究尚需深入。此外，受到研究手段的限制，进行气侧-界面传质模型研究具有一定挑战性。针对当前的相关研究进展和存在的问题，对今后气泡上升行为和传质行为的研究提出以下建议，即开展气泡聚并与破裂可控性研究，强化对气侧-界面传质过程的研究，包括泡内流体行为可视化研究和相关传质模型的建立。 |

| Abstract: | In the industrial processes, rising behavior of bubbles in the liquid and mass transfer on the gas-liquid interface are very common. In this paper, experimental methods and numerical simulation methods are summarized under different conditions. In terms of experiments and numerical simulations, impact factors of single bubble rising behavior, phenomenon and mechanism of coalescence and break up for multiple bubbles, bubble flow pattern and properties in industrial devices, and mass transfer model, especially for gas-interface mass transfer model, are summed up. The results show that the studies about single bubble behavior are sufficient while for the multiple bubbles, more works need to be done. Besides, it is challenging to establish gas-interface mass transfer model due to the limit of research tools. According to the relative research progress and problems, the following suggestions about the future research directions conducting controllability study of coalescence and break up for bubbles, and strengthening of research on gas-interface mass transfer including the research of visualization of the internal flow and convective mass transfer in bubbles. |
| Keywords: | bubble rising behavior mass transfer multiphase flow model |
