Air quality in urban areas has attracted great attention due to increasing pollutant emissions and their negative effects on human health and the environment. The aim of this paper is to analyze the impact of wind on air pollution and human vulnerability by fire products in an urban street canyon caused by a fire accident. For the simulation of a fire on a diesel oil truck a CFD Large Eddy Simulation method was used. Simulation results show that the fire product stream flows vertically upward, without touching the walls of the surrounding buildings in absence of wind. However, when the wind velocity reaches 6 m/s, the product stream curves towards the buildings at both sides of the street canyon. Concentrations of carbon monoxide and soot decrease, while carbon dioxide concentration increases with height. The described scenarios may lead to very serious situations, since circulating fire pollutants can be harmful for the people on the street as well as for those in the buildings with openings oriented toward the street canyon. |
