Accurate estimation of indoor air quality in enclosures is of major importance for achieving healthy indoor environment conditions. The CFD (Computational Fluid Dynamics) approach is currently one of the most used methodology in order to improve the indoor air quality in ventilated environments. As a result, the objective of this study is to evaluate the behavior of CFD simulations for the prediction of indoor air quality in a ventilated test room. The numerical model is based on convection – diffusion equations (to determine the mass fraction of the pollutant), added to the equations used to solve confined turbulent air flows. The computed values are compared with detailed experimental data from the literature, based on tracer gas technique to assess the diffusion of pollutants in a full scale test cell.
