| Abstract | ||
| In this work, CFD simulations were performed to assess the air quality within urban domains through applying one of the ventilation indices for enclosed domains. The index is the Age of Air (AoA), which represents the time consumed by the applied wind to reach a particular point after it enters the considered study domain. The study presents an example of evaluating the air quality of urban areas in terms of AoA. The estimated values of the index were compared to the values of another index which is the purging flow rate. The results of this work confirm that; AoA index of indoor environments is a promising index for the air quality assessment of urban domains as well. | ||
