CFD simulation of the first nozzle of the microfluidic device. Table comparing the pressure drop from the inlet to the first nozzle for a straight and zigzag channel (a). Snapshot of pressure distribution in the first nozzle for the cases in which a zigzag channel or a straight channel is used (b). Simulation of droplet diameter for cases in which the water flow rate (c), or oil flow rate (d) is varied and the other flowrate remains constant
