我们研究了一种用于产生油包水液滴对的微流控双喷嘴。液滴通过两个喷嘴在宽范围的水和油流速下的流体动力学耦合而配对，条件是它们大于通道尺寸。液滴产生频率和体积通过单一的实验确定的幂律与流速相关。的数据是在良好的协议与模型的基础上的几何分解的双喷嘴导致液滴频率作为各种流量的函数的一般方程。
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.
