Abstract
There are many applications of multiphase flow in important fields such as biological, chemical and power processes. Bubble coalescence is of a significant importance in simulating multiphase fluid flows. Weber number (), Reynolds number (Re) and collision parameter play important role in the coalescence of bubbles. In the present work, front-tracking method is applied to simulate bubble coalescence. Moreover, the results are presented for different collision parameters and changes in the coalescence of bubbles are discussed
