Effets de différentes stratégies de ventilation sur les particules en suspension dans l'air intérieur : une étude théorique expérimentale (Effect of ventilation sterategies on particle decay rates indoors : an experimental and modelling study)

The aim of that experimental and modelling study is to determine the impact of different ventilation strategies on indoor particle concentration. For that experiment, polydispersed polyamide powders have been injected in a cubic test-room equipped with a mechanical ventilation system. Then experimental conditions have been simulated in a three dimensional numerical model. The results of the simulation have been compared with the experimental ones and it appears that the particle behaviour is well predicted. But more experimental tests must be made for a better validation of the numerical Lagrangian model.
