Slug bubble deformation and its influence on bubble breakup dynamics in microchannel
文献摘要：
The deformation of moving slug bubbles and its influence on the bubble breakup dynamics in microchan-nel were studied.Three bubble morphologies were found in the experiment:slug,dumbbell and grenade shapes.The viscosity effect of continuous phase aggravates the velocity difference between the fluid near the wall and the bubble,resulting in that the continuous phase near the bubble head flows towards and squeezes the bubble tail,which causes the deformation of bubbles.Moreover,the experimental results show that the deformation of bubbles could significantly prolong the bubble breakup period at the down-stream Y-junction.There exists the critical capillary number CaCr for the asymmetric breakup of grenade bubbles,Cacr increases with the rise of flow rate and viscosity of the continuous phase.
