| dc.description.abstract | 本實驗主要是先將柴油、水和醇類各混入適當的界面劑，挑選特定比例做混合，然後在通入自行組裝的油料混合系統，以高壓空氣壓迫混合液體通過多孔性金屬，期望得到更小更均勻的油滴，以達到穩定的目的。然後以Ink-Jet printing method產生穩定的乳化液自由液滴，進入高溫燃燒爐，觀察液滴的燃燒特性。實驗中第一部分先測試各種比例的柴油、水和醇類的乳化液是否能達到短暫穩定，甚至是更長時間的穩定。第二部分則就乳化液進行燃燒實驗，在固定初始液滴尺寸的情況下，觀察其燃燒現象。並且與單純柴油和水的乳化液以及前人的碰撞液滴燃燒實驗做比較。
實驗結果發現，本實驗的方法的確能使得乳化液更為穩定。並且在柴油比例70%∼60%之間容易產生劇烈的微爆。此外，根據液滴組成機制的不同，同樣的油料比例會產生不同的燃燒現象。 | zh_TW |
| dc.description.abstract | This experiment mainly mingled diesel, water and alcohol with appropriate emulsions respectively, then choose specific proportion for making mixture, injected into the self-fabricated grease mixing system, passed through porosity metal by using high pressure air system to oppress and mix the liquids, expecting convert into more tiny and more homogeneous the oil drops in order to get steady. After that, I use Ink-Jet printing method to generate the droplets in the high temperature environment. We study the Emulsification Stability and the combustion characteristics of the droplets. The first part I will test a short period stability for every proportion of diesel, water and alcohol emulsions, even for a long time. The second part, I run the combustion experiment in the same initial droplets size to observe the combustion phenomenon, and compare with water-in-oil emulsions and the burning experiment of collision-merged droplets.
From the experiment, we find that the method we use can make emulsions more steady. Besides, it’s easily has a violent micro-explosion between the proportion 70%-60% of diesel. Last but not least, based on the different organization of droplets to compose, the same proportion of fuel will creat different combustion phenomenon. | en |
