| dc.description.abstract | Mathematical modeling continues to attract attention of applied math-
ematicians, physicists, engineers, biologists, research institutions and oth-
ers. This study focuses on air pollution concentration: a case study of
y-ash at Sony-Sugar Company, Kenya. Major sources of pollutants in-
clude industrial e uent, agricultural chemicals and tra c vehicle exhaust.
Air pollutants are dispersed by wind into the atmosphere and within an
enclosure. At Sony Sugar factory, air pollution is mainly contributed by
y-ash from unburnt bagasse due to insu cient combustion. This has
had a major negative impact on the surrounding, for instance, on vegeta-
tion and public health. The objective of this study was to determine the
concentration of
y-ash within the boiler chimney at Sony-Sugar factory.
We used a numerical analysis approach that involves two-dimensional
nite element to determine the concentration of the pollutant.We as-
sumed the cross-section of the chimney is polygonal in shape, which was
discretized into small triangular elements. The results obtained may be
useful to engineers, environmentalists, agricultural and industrial sectors,
and research institutions in the assessment, analysis and prediction of
temperature distribution and variation of pressure that can minimize the
pollutant concentration and volume. | en_US |
