Abstract
The liquid–liquid distribution and droplet dynamics in branching T-junction microchannels were studied experimentally. The droplet flow patterns in the main channel are divided into: short-slug flow, long-slug flow and parallel flow. According to the distribution characteristics of droplets in branching T-junction microchannels, it is divided into break up at branching microchannels C1-C4 and break up at branching microchannels C1-C5. The effects of flow rate of both phases and crossing flow on the two-phase distribution uniformity in branching microchannels C1-C4 and C1-C5 are described. Finally, the two-phase distribution in branching microchannels C1-C4 and C1-C5 is analyzed and predicted, and it has achieved a good prediction effect on liquid–liquid two phases distribution in branching microchannels.
