Effects of Unsaturated Components on Droplet Evaporation and Combustion of Biodiesel Fuel Made from Vegetable Oils

Abstract

Evaporation and combustion experiments of a single suspended droplet of palm oil methyl ester (PME) and its components of fatty acid methyl esters (FAME) were performed to obtain fundamental data related to spray combustion. PME droplet evaporation at relatively-low temperatures slows down drastically on the latest stage of evaporation. It is supposed to be due to alteration of the unsaturated FAMEs in PME during evaporation.
