Abstract This research work deals with the computational simulation of the transitions of dripping to jetting which occurs during the flow of Newtonian Fluid. Herein, Volume of Fluid (VOF) model is mapped for the detention of various regimes of drop formation. The transition of drop formation from dripping to jetting is easily categorised through Weber number. The present work reveals that jetting regimes are observed at high Weber number, whereas for the small values of Weber number, dripping and dripping faucet regimes are seen. Critical conditions under which the dripping to jetting transition takes place are arrived by analysing different nozzle diameters subjected to various flow rates.

基于轴对称流动模型的不同过渡阶段液滴不稳定性研究

摘要 这项研究工作涉及牛顿流体流动过程中发生的滴落到喷射转变的计算模拟。在本文中，流体体积 (VOF) 模型被映射用于各种液滴形成机制的滞留。液滴形成从滴落到喷射的转变很容易通过韦伯数进行分类。目前的工作表明，在高韦伯数下观察到喷射状态，而对于小值韦伯数，可以看到滴水和滴水龙头状态。通过分析受不同流速影响的不同喷嘴直径，得出滴到喷射过渡发生的临界条件。
