Coulomb interactions during agglomeration process of soot aerosol nanoparticles

The interest of the scientific community about the agglomeration of aerosol nanoparticles is strongly motivated by the direct implications of this process on the synthesis mechanisms of very different particulate matter, such as soot, silica, titania. In this paper we carry out both experimental and numerical investigation of agglomeration occurring between silicon particles. Aerosol particles are formed by silane pyrolysis in a flow reactor and the coagulation mechanism is observed in the cold downstream zone.
