Abstract
The present work investigates computationally the passage of single and two inline bubbles through liquid-liquid interface. Both the liquids are considered as Newtonian and the volume of fluid approach is used to track the interfaces between the three fluids. The effect of bubble diameter (D⁎), bubble gap (bg⁎) on rupture, retention and coalescence time has been studied. Jet formation and jet breakage is also investigated which depicts that the jet height is more for two inline bubbles in comparison to single bubble for same D⁎. The coalescence stage with different bubble gap (bg⁎) shows that bubbles after coalescence travel faster than that of single bubble rising through the interface. Inline bubbles with higher bg⁎ exhibit all surface phenomena (rupture, entrainment, jet formation) prior to coalescence. The velocity of the rear bubble is seen to be more than the front bubble for all bubble gaps.
