Numerical and Experimental Analysis of Car Exhaust Pollutant Dispersion
The aim of the paper is to compare results obtained by experiments and numerical analysis for vehicle exhaust pollutant emissions and concentrations in urban area. Special attention was plaid to problems of vehicle pollutant emission and dispersion caused by cold start. For description of emission sources a multi-point model was applying. In the model every vehicle is treated as a single moveab...
متن کاملthermal effect on pollutant dispersion in an urban street canyon
his investigation was carried out to reveal the impact of solar radiation on wind flow structure and pollutant dispersion in an urban street canyon of aspect ratio of one using the computational fluid dynamic (cfd) technique. the simulation results (velocity and concentration data) show that heating from building wall surfaces and ground lead to strong buoyancy forces as the air is heated by th...
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 کاملNumerical analysis of a pollutant dispersion in subsurface soil
A hydraulic scale model was used in a laboratory experiment for the purpose of understanding the characteristics of a pollutant dispersion in subsurface soil. The experimental site was an area near a radioactive waste repository in the Republic of Korea. The hydraulic scale model was designed and manufactured in geometric similarity to the actual site. The tracer 99mTc which has a short half-li...
متن کاملSeasonal Changing Effect on Airflow and Pollutant Dispersion Characteristics in Urban Street Canyons
In this study, the effect of seasonal variation on air flow and pollutant dispersion characteristics was numerically investigated. A three-dimensional urban canopy model with unit aspect ratio (H/D = 1) was used to calculate surface temperature distribution in the street canyon. Four representative time events (1000 LST, 1300 LST, 1600 LST and 2000 LST) during typical clear summer and winter da...
