Large-eddy simulation of reactive pollutant dispersion in a street canyon using a subgrid scale variance model of concentration field
ABSTRACT: Bi-molecular reactions can affect the transport of air pollutants in urban street canyons. In numerical simulations, we need to evaluate the correlation between the concentrations of the reactants to know the reaction rate. In this paper, we examine the effects of the subgrid scale (SGS) on the reaction rate in large-eddy simulations (LESs). LESs coupled with an SGS variance model are...
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...

15 صفحه اولPrediction of Pollutant Emissions from Industrial Furnaces Using Large Eddy Simulation
Accurate prediction of pollutant emissions from turbulent combustion around complex geometries is of great practical interest. Here, an industrial furnace with rich-burn/quick-quench/lean-burn combustion for NOx reduction is simulated. Large eddy simulation (LES) is employed as the simulation tool since it outperforms Reynolds-Averaged-Navier-Stokes (RANS) simulations in capturing large-scale u...
متن کاملTransport Phenomena in the Urban Street Canyon
1 Abstract A generic proecological traffic control model for the urban street canyon is proposed by development of advanced continuum field hydrodynamical control model of the street canyon. The model of optimal control of street canyon dynamics is also investigated. The mathematical physics' approach (Eulerian approach) to vehicular movement, to pollutants' emission, and to pollutants' dynamic...
