In the field of the fabrication of micro- and nano-spheres, the phenomenon of Plateau-Rayleigh instability has drawn more and more attention. This surface tension-driven instability in two immiscible fluids can be used to generate uniformly size micro- and nano-spheres by imposing an external mechanical excitation. In this article, we mainly adopt numerical simulation method to study the effects of...
This paper reports a microfluidic reactor for synthesizing micro- and nano-droplets using fluid shearing instability of immiscible flow in mircochannels. Three factors, flow rate between the two inputs, spout geometry and surface tension are numerically studied. Based on the simulation, a device with the optimal parameters was fabricated and tested. Both computational fluid dynamics (CFD) simulation...
