CFD Simulation of Automotive Pollutant Dispersion in High-Rise Building Urban Environment Under Deeply Stable Atmospheric Condition

CFD simulation of near-field pollutant dispersion in the urban environment: A review of current modeling techniques

Near-field pollutant dispersion in the urban environment involves the interaction of a plume and the flow field perturbed by building obstacles. In the past two decades, micro-scale Computational Fluid Dynamics (CFD) simulation of pollutant dispersion around buildings and in urban areas has been widely used, sometimes in lieu of wind tunnel testing. This paper reviews current modeling technique...

numerical simulation of plume rise in neutral atmospheric stability condition

introduction air pollution has harmful effect on human health and the environment. accordingly, considerable effort has been put to analyze the air pollutants. one important issue is the spatial distribution of these pollutants. dispersion of the pollutants released from sources on the ground is mostly driven by the planetary boundary layer where turbulent flow causes mixing of the content of t...

Microscopic modeling for atmospheric urban pollutant dispersion in dense urban road networks

Flow and Pollutant Dispersion in Urban Arrays for the Standardization of Cfd Modelling Practise

The study of the effect of obstacles on flow and dispersion in the atmospheric boundary layer is one of the most important topics in atmospheric dispersion research. Computational Fluid Dynamics (CFD) methods are increasingly used to predict concentration fields near buildings in an operational context, but extensive validations are still needed. In this paper, we analyse the effect on flow and...

Atmospheric dispersion model to predict the impact of gaseous pollutant in an industrial and mining cluster

Dispersion modeling approach was applied for the determination of SO2 and NO2 pollution in the ambient air. The model performance has been evaluated by comparing the measured and predicted concentrations of SO2 and NO2. This has been tested to measure the air quality and predicted incremental value of pollutant’s concentrations by using the data avail...
