PARTICLE TRACKING MODEL OF SULPHUR DIOXIDE IN A FLOW THROUGH A POROUS MEDIUM

The transport of contaminants emanating from localized sources such as factories and agricultural farms in porous media, is of hydro dispersion phenomena, has been the major subject for more than four decades. Because of industrial and agricultural activities, inorganic wastes mainly biodegradable and non-biodegradable substance example sulphur dioxide, oil spills, human wastes, fertilizers among others percolates through porous media and eventually find their way to water bodies like stream, rivers and boreholes. This research study aims to describe numerically a particle tracking model of sulphur dioxide in a flow through a porous media from Chemelil milling wastes (molasses) and agricultural inputs example fertilizers, fungicides, herbicides with respect to concentration between two points, concentration along the contour field and velocity and effects of decay and sorption in three dimension. The governing equation of three-dimensional concentration distribution in fluid flow through porous media will be determined in terms of three-dimensional non-linear advection-dispersion equation. Finite Difference Method will be used to solve the MATLAB software will be used to validate the results using data from Chemelil factory as the source point.
