Abstract

PAH are considered as dominant precursors to soot formation in diffusion flames. Ethylene/propane diffusion flame experiments demonstrated the synergistic effect on soot formation process. This was explained with the role of HACA mechanism and C₃ recombination reactions during the ring formation process for incipient PAH. The distributions of distinguished PAH in ethylene/propane diffusion flames at different wavelengths (240-550 nm) were determined using a planar laser induced fluorescence technique (PLIF) to better understand the role of C₂ and C₃ species in formation and growth of PAH. Ethylene/propane diffusion flames were produced using a laminar co-flow burner. The spatial distribution of fluorescence signal was changed with incident and receiving wavelength. The PLIF images of PAH at different wavelengths exhibited the distinguished synergistic behaviors with ethylene/propane ratio. Original is an abstract.
