On Classification of Water-in-Oil and Oil-in-Water Droplet Generation Regimes in Flow-Focusing Microfluidic Devices

The objective of this research work is to propose a phase diagram that can be used find proper operating condition for generating droplets different types. It found the QR versus CaD effectively classify droplet generation into three vivid regimes: dripping, jetting and tubing. For dripping regime, its in range either < 10−4 50 or 10−3 1. 1.35 × 10−2 > 100 tubing
