Abstract
Air quality is a growing concern for the health of the global population living in
large urban centres. The goal of this paper is to present methods and experiences
concerning wind tunnel investigations carried out on a 1:500 scale model of a
large neighbourhood of Geneva for a typical wind condition. Gas dispersion
phenomena were reproduced in the wind tunnel by a mixture of air and SF6
released from 150 continuous point sources on the model building rooftops.
Measurements of the 3D aerodynamic field and pollutant concentration were
performed in order to validate a CFD open-source code. This experimental
campaign is part of the long-term research project called Clean City and was
undertaken at CMEFE laboratory of hepia (Haute Ecole du Paysage, d’Ingénierie
et d’Architecture de Genève), University of Applied Sciences of Western
Switzerland.
Keywords
wind tunnel measurements, air quality, pollutant dispersion, builtenvironment, air pollution aerodynamics.
