Abstract

This abstract presents computational fluid dynamics (CFD) simulations of indoor gaseous pollutant transport using the Reynolds-averaged Navier-Stokes (RANS) approach. Case I consists of mixing ventilation in a cubical enclosure, while case II focuses on cross-ventilation in a rectangular enclosure. It is shown that steady RANS combined with an advection-diffusion equation for pollutant transport can fairly accurately predict gaseous pollutant concentrations in the generic enclosures studied. The results in case I are compared to a high-resolution large eddy simulation (LES), while in case II the results are compared to experiments.
