Analysis of Chlorine Gas Incident Simulation and Dispersion Within a Complex and Populated Urban Area Via Computation Fluid Dynamics
In some instances, it is inevitable that large amounts of potentially hazardous chemicals like chlorine gas are stored and used in facilities in densely populated areas. In such cases, all safety issues must be carefully considered. To reach this goal, it is important to have accurate information concerning chlorine gas behaviors and how it is dispersed in dense urban areas. Furthermore, mainta...

متن کاملNumerical Simulation of Pollutant Dispersion from Point Source in an Urban Area
In this paper, pollutant dispersion from point source was investigated numerically in an urban area. Numerical simulations were carried out using Computational Fluid Dynamics (CFD) models. The CFD models used for the simulation were based on the steadystate Reynolds-Average Navier-Stoke equations (RANS) with κ-ε turbulence models. A gas pollutant was emitted from a point source within the wake ...
متن کاملPollutants emissions in a urban area: definition of emission factors, atmospheric dispersion modelling and support of intervention policies
Within a urban context, the most important pollutants that should be studied and reduced in a urban context in order to ensure the sustainability of the metropolitan environment are NOx and PM10. While the emission factors for NOx are well known for all the sources, the PM emission from traffic are of two types, exhaust and nonexhaust. The latter type of emission is due to vehicle components’ w...
