Abstract
In many instances hazardous materials are to be transported across urban areas, as no viable alternatives exist. The high threat to human health that may result makes it important to develop methods for its quantification and assessment. Due to the semi-confined nature of the dispersion site (a network of city roads with buildings on their sides) simplified models are unsuitable. The problem then arises of developing complex models in order to quantify the extent of the area affected by dangerous concentrations during cloud dispersion. In the present work the same CFD model is applied to the simulation of heavy pollutants dispersion in a real urban canopy located in Sicily (Italy), with the aim of showing the potential and drawbacks of CFD tools for the above detailed risk assessments.Pubblicazioni consigliate
