CFD modeling of vegetation barriers to improve air quality

This study aims to design effective vegetation barriers, including hedges and trees, to improve air quality behind them. To achieve this objective, Computational Fluid Dynamic (CFD) modelling is applied to an avenue with hedges and trees in one sidewalk located in Pamplona (Northern Spain). Firstly, model results are evaluated by means of an experimental campaign carried out in this zone. Then, several scenarios are simulated changing the vegetation configuration in order to analyse its influence on concentration distribution behind the barrier.
