The evolution of incipient soot particles in an inverse diffusion flame of ethene

摘要

Soot formation from fuel combustion involves complex chemical and physical processes including fuel pyrolysis, polycyclic aromatic hydrocarbon (PAH) formation, particle inception, coagulation, surface growth, carbonization, agglomeration, and oxidation [1-4]. Although soot evolution processes have been investigated and successfully modeled in many studies, more information on soot inception is still necessary in order to improve the understanding of the entire soot-evolving process.
