Breaking one into three: Surface-tension-driven droplet breakup in T-junctions

We report a novel droplet breakup regime in the microfluidics T-junction, where new interfaces are created two arm channels, rather than at center of junction. show that there is different hydrodynamic root for this regime, and propose simple geometric rule which enables compared to classical T-junction. A dynamic model lower capillary number (Ca) developed predict process. also higher Ca central recovered same
