Coagulation of polydisperse primary particles is the dominant agglomerate growth mechanism in flame reactors and the low-temperature or high-pressure regions of combustion engines. Here, Eirini Goudeli discusses the evolution of agglomerate size distribution (SD) and collision frequency function of coagulating soot and silica primary particles is investigated with simultaneous surface growth or coalescence using discrete element modeling (DEM).
