Reduced Chemical Kinetic Mechanism for Methyl Pentanoate Combustion

A reduced mechanism for the combustion of methyl pentanoate (MPe), consisting of 330 elementary reactions involving 92 species, has been developed based on the previously proposed combustion mechanism for MPe using the Mechanism Workbench software. The reduced model has been validated against experimental data on the structure of burner-stabilized stoichiometric and fuel-rich MPe/O2/Ar flames at pressures of 20 Torr and 1 atm. The modeling results for the full and reduced mechanisms are in good agreement for major flame species and for most of the intermediates, including hydrogen, methane, methyl radical, ethylene, acetylene, propyne, butadiene, methyl propenoate, and other intermediates. The proposed kinetic model also was validated against experimental data on MPe/air flame propagation velocities and extinction strain rates at atmospheric pressure as well as the autoignition delay times of stoichiometric MPe and air mixtures at T = 815 K and pressures of p = 10–18 bar.
