Hydrodynamically mediated breakup of droplets in microchannels

Zhizhao Che (车志钊), Nam-Trung Nguyen (阮南忠), and Teck Neng Wong (王德能) A flow focusing junction is integrated into a microchannel to break up droplets into a controllable number and size of daughter droplets. High speed images of the breakup at the flow focusing junction show that the breakup depends on the interplay between interfacial tension, shear force on the inte ... [Appl. Phys.
