In the present work, a diesel pool fire incident inside a street canyon is studied numerically. The flow inside the street canyon, the smallest urban unit, and the pollutant fire dispersion are studied with a Large-eddy Simulation method. The method is compared fairly well against experimental data. Cases with different inflow wind speeds are studied and the risk zones are defined for the different wind approaching scenarios. Results show that part of the fire pollutants exits the canyon, while another part is trapped into the canyon due to the local air recirculation. The buoyancy effect due to the fire incident and the inertial effect of the wind flow define the pollutant’s dispersion. When the wind velocity at the street canyon height exceeds a critical value, the fire pollutants are recirculated and trapped inside the street canyon. This dispersion is analysed based on the flow characteristics in the street canyon.
