We study a microfluidic dual nozzle for the production of water-in-oil droplet pairs. Droplets are paired by the hydrodynamic coupling of two nozzles over a wide range of aqueous and oil flow rates provided that they are larger than the channel dimensions. The droplet production frequencies and volumes are related to the flow rates through a single, experimentally determined power-law. The data are in good agreement with a model based on a geometrical decomposition of the dual nozzle leading to a general equation of droplet frequencies as a function of the various flow rates.
我们研究了一种用于生产油包水液滴对的微流控双喷嘴。在水相和油相流速范围很广的情况下，只要液滴大于通道尺寸，两个喷嘴的流体动力耦合就能使液滴配对。液滴的产生频率和体积通过一个单一的、实验确定的幂律与流速相关。这些数据与一个基于双喷嘴几何分解的模型高度吻合，该模型得出了液滴频率作为各种流速函数的通用方程。
