Soot modeling of counterflow diffusion flames of ethylene-based binary mixture fuels

A soot model was developed based on the recently proposed PAH growth mechanism for C1–C4 gaseous fuels (KAUST PAH Mechanism 2, KM2) that included molecular growth up to coronene (A7) to simulate soot formation in counterflow diffusion flames of ethylene and its binary mixtures with methane, ethane and propane based on the method of moments. The soot model has 36 soot nucleation reactions from 8 PAH molecules including pyrene and larger PAHs....
