Abstract
Air pollution levels can be estimated using different estimation techniques, such as; sampling or direct measurement, mass balance, fuel analysis or any other engineering calculations and emission factors. Furthermore, it is also important to understand how the smoke spreads and affects the surroundings. For this analysis, the computer code called PHOENICS is used. In PHOENICS a suitable control volume representing an actual area under investigation is used for the analysis. Parameters associated with the flow of smoke such as air velocity and pressure are also analyzed. The results of this analysis have shown that air velocity and pressure have an effect on the transport of smoke. High velocities and low pressures have a suctioning effect on the flue gas stacks hence easily carrying away the smoke produced. This does not however, mitigate the disastrous effects of the pollutants. The pollutants have only been carried from one region to another.
