Abstract

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 QR versus CaD can effectively classify the droplet generation into three vivid regimes: dripping jetting and tubing. For the dripping regime its operating condition is in the range of either CaD < 10?4 and QR < 50 or 10?3 < CaD < 10?4 and QR < 1. For the jetting regime its operating condition is in the range of either CaD < 1.35 ? 10?2 and QR > 100 or CaD > 1.35 ? 10?2 and QR > 1. For the tubing regime its operating condition is in the range of CaD > 1.35 ? 10?2 and QR < 1. ? 2023 by the authors.
