Bubble dynamics and interface phenomenon

The dispersion of gas into liquid is a complex part and it is depending on bubble size and its distribution including coalescence and breakup. The study of flow pattern, bubble size and its distribution and factors affecting the bubble size was reviewed by several authors. Various measurement techniques of bubble size are also reported in literature. In this paper we have made an attempt to show the literature survey on bubble dynamics as it plays very crucial role in mass transfer characteristics.   Key words: Computational fluid dynamics (CFD), multiphase flow gas-liquid two-phase flow, bubbly flow, bubble size distribution, Sauter-mean bubble diameter, mean bubble size, bubble breakup and coalescence, free surface flow, slug flow.
