Development of a user-friendly software package for predicting the concentration of pollutant in the atmosphere from chimney emissions in urban environments
The software package being developed in this project will assist in the design and modification of existing industrial exhaust ventilation systems in large conurbations. The package will be of immense environmental benefit to companies which monitor pollution emissions, such as the British Textile Technology Group which monitors exhaust emissions for industry and advises on how to meet HMPO health and safety guidelines. It will also allow industry to better understand the interaction of their chimney emissions with the local environment and hence, how to minimise the contamination caused. The general public will also have a cleaner environment in which to live, due to the improved understanding of pollution dispersion by industry.
The project is using a mathematical and computational fluid dynamics (CFD) approach, which will be validated against both existing and new data obtained in the field. Numerous CFD models have recently been developed to investigate the effects of pollution released from chimneys. However, most of these studies have been restricted to rural situations, in which, local topography is not important. Some have also been validated by performing experiments in large wind tunnels. Recent research work at Leeds has shown that these CFD models are inappropriate if the rotation of the earth, although small, is not taken into account. Furthermore, the research work at Leeds has involved investigating the effect of the local topography on the air flow in the region of the pollution emission.
The CFD modelling being undertaken will be appropriate to any conurbation. However, it is being concentrated on Leeds where detailed measurements of pollution emissions are either in existence or where experimental data can be obtained in the near future.
