Graphical Abstract:


Background: With the deep investigation on hydrodynamics of bubbly flows, the influence of bubble coalescence and break-up phenomena on hydrodynamics has been paid more attention in the academic circle. In order to well understand and to promote the further investigation on the bubble coalescence and break-up phenomena, some related model and mechanisms are reviewed in this paper.

Objective: Comprehending mechanisms of bubble coalescence and break-up under different circumstances and establishing an appropriate model are the foundation of study. A variety of bubble coalescence and break-up models and the corresponding mechanisms are reviewed and analyzed in this paper.

Methods: According to the present references, this paper has reviewed and analyzed Eulerian-Eulerian single average quantities model, Eulerian-Eulerian multiple size group model and Eulerian-Lagrangian multiple size group model as well as their balance equations and mechanisms in detail.

Results: After analyzing these various models and mechanisms, merits and drawbacks for different models are presented in this paper. Besides, in order to be convenient to perform further studies on bubble coalescence and break-up phenomena so as to establish a more perfect model, patents proposed by our research group related to catching and controlling bubble coalescence phenomena are also included in this paper so that the related researchers can get some hints from them.

Conclusion: It can be seen from the present review that the model and mechanism on the bubble coalescence and break-up phenomena are different for different researchers, and each model has its own limitation and the given mechanisms are rough. Therefore, it is necessary to have a more thorough study on bubble coalescence and break-up phenomena with the help of the proposed patents.

Keywords: Bubble coalescence, bubble breakup, models, mechanisms, patents, hydrodynamics.
