Validation of a coupled multizone CFD Program for building airflow and contaminant transport simulations

A coupled multizone-CFD program has been developed for that study with the aim to improve the multizone model by applying a CFD model to the poorly mixed zones and the multizone model to the remaining zones. By using experimental data, the coupled multizone-CFD program is validated. The calculated results obtained by the coupled program generally agreed with the experimental data, though discrepancies exist in some cases.
