Abstract

In this study, aerosol deposition of nanoparticles on flat surfaces has been investigated by Langevin dynamics (LD) accounting for Brownian's diffusion and a fix translational velocity. The particles are assumed to drop one at a time and had a monodisperse size distribution. The detailed morphology of the nanoparticle films was investigated as a function of Pe number, the ratio between Brownian and translational displacement for different structural constrains. The porosity was reduced with increasing Pe number from the diffusion to ballistic deposition limit. It was found that the simulation constrains have a substantial impact on the resulting film structural properties. This was attributed to the multi-scale porosity of these aerosol-deposited films.
