Abstract

Fatty acids esters are the main biodiesel components. Experimental studies, especially at atmospheric and higher pressures, are of great importance for combustion models development. In this work, we studied near-stoichiometric and rich flames of two isomeric esters - ethyl acetate (EA) and methyl propanoate (MP). We did experiments to study EA/O2/Ar and MP/O2/Ar flame structure at atmospheric pressure. For numerical simulation, we used two published mechanisms for esters oxidation. Significant differences between experiment and modeling and between models arise for some intermediates. Analysis of fuels decomposition reaction paths shows MP to decompose mostly in radical reactions. Besides radical reactions, EA undergoes monomolecular decomposition with ethylene and acetic acid formation.
