Abstract
Combustion characteristics of a 1-butanol gel fuel were studied in atmospheric pressure condition. The butanol gel fuel was manufactured by adding hydroxypropyl-methyl cellulose (HPMC) as a gellant and the effect of the gellant concentration was observed. The combustion process of a single butanol gel droplet was divided into 3 stages including droplet heating, microexplosion, and gellant combustion. The flame was distorted compared to butanol + water mixture because of micro-explosion during the combustion. Increase of gellant concentration delayed the droplet ignition, but the combustion rate was improved due to the mass ejection during the micro-explosion.
