Assessment of a model for aggregation, transport and deposition of low-inertia particles in a ventilated chamber

This article focuses on the assessment of a model that allows tracking the dynamics of an aerosol in two different cases: first for microparticles (with a mean size of 10 micrometers) in a ventilated chamber for evaluating advection, diffusion, deposition and sedimentation phenomena, then for nanoparticles (with a mean size of 50 nanometers) in a ventilated chamber for evaluating advection, diffusion, deposition and aggregation phenomena. The first case is issued from the literature and the second case corresponds to a new experimental set-up. The use of nanoparticles leads to considering specific measurement techniques that are also briefly described for analyzing the shape of expanded aggregates. Regarding the first results, the model seems able to track the change of aerosols from the nano- to the micro-scale, keeping good computational performances that allow industrial applications.
