摘要: Marangoni效应广泛存在于液液、气液相际传质过程中,通常会对传质速率产生重要影响。对Marangoni效应的实验及理论研究有助于增进对微观传质机理的理解,是强化相间传质过程效率的重要因素。重点介绍了液液体系中单液滴萃取的实验和模拟研究,对液液体系中Marangoni效应不稳定性的判据,对气液体系有效传质面积的影响,以及两种体系中利用表面活性剂进行传质调控的研究等方面的进展进行了综述,还探讨了传质过程中Marangoni效应应用研究的方向。

Abstract: Marangoni effect, occurring frequently in interphase mass transfer processes in liquid-liquid and gas-liquid systems, plays an important role in determining the mass transfer rate.Experimental and theoretical studies on Marangoni effect will enhance the understanding on microscopic mechanism of interphase mass transfer and help in optimizing the operation of mass transfer units.The reported results on the criterion of instability in liquid-liquid systems, effective mass transfer area in gas-liquid systems, manipulation of Marangoni effect using surfactants in both systems, especially single droplet extraction, are reviewed.The topics of future study are also suggested.

Key words: Marangoni effect, mass transfer, surfactant, droplet, bubble, numerical simulation
