摘要: Abstract A novel model called Surface Shell Formation (SSF) is developed which predicts soot maturity based on the equilibrium nanostructure of poly aromatic hydrocarbons (PAHs) inside primary particles. The characteristic isotropic core-graphitic shell internal particles used to distinguish nascent from mature new sectional track particle Hydrogen Carbon (H/C) ratio and growth in molecular weight PAHs An independent Arrhenius term describes dehydrogenation/carbonization. It shown that depends both size H/C ratio. Graphitic formation related surface change configuration edge for face validated against experimental data laminar premixed, partially premixed diffusion flames. SSF model addresses two major limitations current modeling approaches. First, it by considering carbonization. Second, distinguishes presence graphitic shell.
