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.
