Numerical Simulation of Wind Borne Pollutants Dispersion
Supervisors: Dr S B Chin, Dr F C G A Nicolleau
Waste disposal in the open environment (from, for example, composting and landfill sites) produces potentially harmful agents which may become airborne, affecting public or worker health. Such agents may be biological (bioaerosols), dust and odours. Industrial sites such as chimneys and open cast mining eject dust and particles which are borne by the prevailing wind to affect remote locations. Health and safety measures require knowledge of how far and wide these pollutants may spread.

The research will employ computational fluid dynamics technique in the first instance to examine the effects of the interaction of the atmospheric turbulence, meteorological conditions and topographical factors in the dispersion of these pollutants. Factors which may be considered in the simulation may be:

1) Bioaerosols dispersion
2) Odour dispersion
3) Effects of local terrain (eg hills and tree clusters, river, buildings)
4) Effects of numerical factors
5) Suitability of physical models (eg dispersion, turbulence model, source terms)
