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.
