Comparison of Different Turbulence Models Applied to Modelling of Airflow in Urban Street Canyon and Comparison with Measurements
Residential buildings in cities are ventilated using different systems for ventilation. Except for systems that consist in opening windows, there are more sophisticated systems that are controlled by different manners. Among them, hybrid systems are recently gaining more attention as they promise to be energy effective with a good control of indoor air quality. Operation of such ventilation systems can be significantly influenced by airflow in street canyons. Thus, correct prediction of airflow is a prerequisite for efficient functioning of such systems. Authors of this paper choose Agiou Fanouriou street canyon in Athens as a test canyon for comparison of modeling and field measurements.
