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