Description	The CFD code StarCD was used for airflow modeling in an urban street canyon. A numerical model of a calculated area involves not only the studied street canyon but also surrounding buildings. Series of calculations were done for three different wind directions, namely longitudinal, perpendicular and oblique wind direction. The wind direction orientation is related to the longitudinal axis of the studied street canyon. Velocity fields were solved for wind velocities 3 m/s and 6 m/s as obtained from the measurements at height 25 m above ground level. In total, three different turbulence models were tested. As a first one, K- Hi-Re model was used as the most common model used in CFD. As a second, K- RNG model of turbulence was taken into account. From different studies it follows that this model provides good results of air flow in urban areas. Third, the K- Lo-Re model of turbulence (Lien, F.S., Chen, W.L., and Leschziner, M.A., 1996) was used.
