利用壓電致動器成形之微形液滴研究

The study on the micro liquid droplet actuated by piezoelectric transducer

指導教授 : 王興華

摘要


本文主要利用一自行設計之壓電式液滴產生器,以控制產生的方式產生液滴,經由影像擷取系統拍攝液滴產生的過程,並藉由調整不同的參數(電壓與頻寬),找出各種不同口徑之噴嘴與不同致動模式下,液滴產生器可產生穩定液滴與衛星液滴之範圍,以及液滴之粒徑分布與液滴形成時間。並藉由製作液滴產生之時序圖,探討主液滴與衛星液滴產生的機制,與衛星液滴對於液滴產生之尺寸與形成時間所造成的影響。

並列摘要


This article focus on the process of droplet breakup and the formation of satellite droplet. By the method of Drop-On-Demand (DOD) to generate droplet, we design a piezoelectric droplet generator. This work will analyze droplet generated under different controlled parameters (voltage and pulse width). We map the regime of the formation of stable single droplet and satellite droplet under different actuate modes and different nozzle diameters. Droplet size and broken time are also been discussed here. We also make images of the sequence of droplet formation. These will help us understand the mechanism of droplet breakup and the influence of satellite droplet
