Impact of the competition between aggregation and surface growth on the morphology of soot particles formed in an ethylene laminar premixed flame

Soot particle surface growth may have a significant impact on aggregation kinetics, morphology, and both aggregate monomer size distributions. Particularly, the morphological effects of are currently poorly understood. This is complex since also affects kinetics resulting in time-dependent competition between phenomena, producing very different markers. The present study aims at improving our understanding by implementing this effect Monte Carlo discrete element code for simulation soot formation an ethylene premixed flame. An asymptotic average primary overlapping ?30% observed flame conditions. coordination number highly sensitive to rate volume fraction, maximum values within 4 - 8 range. local compacity, as quantified packing factor, considerably increased when aggregates experience growth, contrarily fractal structure individual that seems more dependent regime. Finally, narrows
