Abstract

This study proposed a chemical kinetic model for PAH growth up to A7 for gasoline surrogate fuels. The proposed model was first validated against n-heptane and iso-octane premixed flame data available in the literature. The proposed model also well reproduced the experimentally observed synergistic effect on A1-A3 PAHs deduced from LIF signals, and the monotonic increase of A4-A7 deduced from LII signals in counterflow n-heptane/toluene and iso-octane/toluene diffusion flames. In order to better understand the synergistic effects of binary mixtures, reaction path analyses were conducted to identify important reactions to form PAHs. New experiments were also performed using a counterflow n-heptane/iso-octane diffusion flames and the results indicate the non-linear increase of soot volume fractions. The computed maximum mole fractions of A7 are in good agreement with the experimental trend.
