Abstract: | 本實驗利用陶瓷纖維將液滴掛於其交點處,在重力場下觀察不同沸點的油料混合後,其液滴的燃燒行為與特性,本實驗所使用的雙組份油料有生質柴油/大豆油、生質柴油/玉米油、生質柴油/葡萄籽油、生質柴油/乙醇。
實驗結果顯示,生質柴油與大豆油因性質類似,所以產生微爆與火焰縮口的現象不如其他兩種生質油料頻繁;當生質油料與生質柴油之沸點差距不大,則液滴在發生微爆後,仍可繼續維持球對稱燃燒。而乙醇/生質柴油之雙組份油料,則會出現許多不同的現象,其為點火溫度差異性所導致,因乙醇與生質柴油沸點差異極大,所以當發生微爆後,液滴則會炸開破裂,變成許多熄滅的小液滴。 Experiments make suspended droplets include binary fuels of different boiling point , and observe characteristics of the combustion. The binary fuel mixtures used in this experiment were biodiesel/soybean oil, biodiesel/corn oil, biodiesel/ grapeseed oil, and biodiesel/ ethanol. This experimental results showed the variation of micro-explosion and flame shrinkage were slight , because the property of biodiesel and soybean oil were similar. After the micro-explosion of droplet , it still keep spherical symmetry on combustion ,when boiling point of bio oil and bio diesel were similar. Biodiesel/ ethanol fuel on different heating temperature will cause varied status , after the micro-explosion of droplet , it will burst and become numerous extinction little droplets , when boiling point of ethanol and bio diesel were different. |
