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.

流动聚焦微流体装置中油包水和油包水滴生成机制的分类

本研究工作的目的是提出一个相图，该相图可用于寻找生成不同类型液滴的合适操作条件。研究发现，QR - CaD相图可以有效地将液滴的生成划分为三种生动的形式:滴、喷、管。滴漏工况在CaD < 10−4,QR < 50或10−3 < CaD < 10−4,QR < 1范围内。对于喷射工况，其运行工况在CaD < 1.35 × 10−2和QR >00或CaD > 1.35 × 10−2和QR > 1范围内。对于油管工况，其工况范围为CaD 1.35 × 10−2,QR < 1。
