INVESTIGATION OF METHYL PENTANOATE FLAME STRUCTURE BY MOLECULAR-BEAM MASS SPECTROMETRY AND MODELING

Read more The structure of four stoichiometric and fuel-rich premixed flames of methyl pentanoate stabilized at low (20 torr) and atmospheric pressures has been studied by molecular-beam mass spectrometry. The data obtained have been compared with results of numerical simulations, performed with implication of two detailed chemical kinetic mechanisms, one of which has been developed by the authors of this work. While both mechanisms have predicted concentration profiles for most of the species quite well, some discrepancies between experimental and modeling data have been observed for carbon monoxide and some intermediate products. Considerable differences in several profiles simulated with different mechanisms have been noted. Analysis of reaction paths in investigated flames has shown most of these differences to be caused by different reactions and kinetics used for isomerization of primary radicals of methyl pentanoate oxidation in these mechanisms.
