摘      要：The high-throughput production of monodisperse droplets is paramount in most of the applications in droplet *** a flow-focusing junction,a straightforward way to increase droplet production rate is to increase the flow ***,at a critical flow velocity,the droplet monodispersity breaks down due to a transition from the dripping to the jetting *** a result,a much more polydisperse droplet population is *** change from monodisperse to polydisperse droplet production emerges from the intrinsic properties of the instabilities of *** the jetting regime,droplet pinch-off is governed by a convective instability which amplifies random noise when traveling down the jet leading to an irregular *** show that with the use of an amplitude-modulated electric signal,we select the breakup frequency of the *** the perturbation frequency close to the natural breakup frequency of the jet,we increase the monodispersity of the droplet *** method is applicable to droplet production at a high throughput,that is,beyond the dripping to jetting threshold,including an active control since the frequency,and hence droplet sizes,are determined by the forcing frequency.
