Aim of this work is to further validate a general detailed mechanism of pyrolysis and oxidation for the high temperature combustion of a large variety of different fuels. The attention is first placed on the validation of the chemical mechanism in respect of the laminar flame speed of H2 and H2/CO mixtures as well as the burning velocity of small hydrocarbon fuels such as methane and C2-C4 species. Alkanes, alkenes and alkynes are considered, together with butadiene. Reference fuels for gasoline and jet fuel surrogates are also analysed. More specifically, three hydrocarbon classes are considered: alkanes (n-heptane: nC7H16 and iso-octane: iC8H18, and higher n-alkanes: nC10H22 and nC12H26), cyclo-alkanes (cyclo-hexane) and aromatics (benzene: C6H6, toluene: C7H8). Finally, burning velocity of C1-C4 alcohols are also compared with experimental data.

Abstract

Aim of this work is to further validate a general detailed mechanism of pyrolysis and oxidation for the high temperature combustion of a large variety of different fuels. The attention is first placed on the validation of the chemical mechanism in respect of the laminar flame speed of H2 and H2/CO mixtures as well as the burning velocity of small hydrocarbon fuels such as methane and C2-C4 species. Alkanes, alkenes and alkynes are considered, together with butadiene. Reference fuels for gasoline and jet fuel surrogates are also analysed. More specifically, three hydrocarbon classes are considered: alkanes (n-heptane: nC7H16 and iso-octane: iC8H18, and higher n-alkanes: nC10H22 and nC12H26), cyclo-alkanes (cyclo-hexane) and aromatics (benzene: C6H6, toluene: C7H8). Finally, burning velocity of C1-C4 alcohols are also compared with experimental data.
