Abstract:In this work, the droplet generation process in the microfluidic step emulsification chip with a triangular nozzle (SE‐T) was investigated in the combination of visualization experiment and numerical simulation, through a comparison with a rectangular nozzle (SE‐R). The flow regimes, including dripping, dripping‐jetting transition, and jetting, were observed in the SE‐T, among which the dripping is the preferred flow regime to generate monodispersed droplet with corresponding C.V. (coefficient of variation) of… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
