Abstract
In this study, the validity of the moment method and sectional method that have been used as particle formation calculation was investigated numerically. Both methods were tested for the recent experimental data of the soot formation in C_3H_8/air mixture by a shock tube. CHEMKIN-PRO with the recently proposed PAH growth mechanism for C1-C4 gaseous fuels (KAUST PAH Mechanism 2, KM2) that included molecular growth up to coronene was used for the soot formation calculations. The computed soot characteristics such as mean particle diameter, soot yield etc. were compared between moment method and sectional method.
