Abstract
The primary objective of our study is to clarify the effect of alcohol additions on combustion processes of a FAME droplet. Experimental study has been carried out to discuss a statistical characteristics of occurrences of secondary atomization of a burning FAME droplet with methanol additions. Oleic acid methyl ester (OME) is used as FAME of test fuels. It is indicated that the secondary atomization including puffing and micro-explosion occurs in the combustion processes of OME/methanol droplet, and droplet life time is dominated by occurrence of secondary atomization. It is also discussed that effect of exposure time of suspended droplet on changes of internal phase and ratio of micro-explosions.
