Charged droplet formation in a co-flow microchannel with effect of electric field
This study experimentally investigated the droplet formation process under the effect of an electric field in a coaxial microchannel. Depending on the flow rates, the well-known squeezing, dripping and jetting patterns were observed. However, the effect of electric field significantly altered the flow rate ranges at which these regimes occurred. The droplet size was found to scale with the electric Bond number and the phase flow rate ratio, while two regimes emerged for the droplet size: one governed by the hydrodynamic flow field and the other governed by the electric field.
