Abstract: Liquid-liquid jet mixers have good micro-mixing characteristic which well match the liquid-liquid fast reaction system. It's significant to choose proper methods and quantitative indexes to study the micro-mixing characteristic of various jet mixers. In this work, common methods (chemical probe technique, LIF technique and CFD) to study the micro-mixing characteristic in liquid-liquid mixing system were compared, including their merits and demerits, the range of application, the selection principles and application key points. Meanwhile, the related quantitative indexes were also summarized. Then the liquid-liquid jet mixers were systematically classified. Based on this, the key factors that influence their micro-mixing characteristic and research progress in various jet mixers were further analyzed. The latter contained the application progress of aforementioned three methods on study micro-mixing mechanism, micro-mixing characteristic time, micro-mixing intensification and structure optimization. Finally, the limits of present research on the micro-mixing characteristic of tank jet mixers and tubular jet mixers were concluded and the trend of further research was also noted.

Key words: liquid-liquid jet mixers, micro-mixing, chemical probe technique, LIF technique, CFD
