Abstract

This paper numerically investigates the effect of point source pollution discharged from intentional release flowing into waters. The consequences of such contamination on ecosystems are very serious. Accordingly, effective tools are highly demanded in this respect, which enable us to come across an accurate progress of pollutant and anticipate different measures to be applied in order to limit the degradation of the environmental surrounding. In this context, we present a predictive hydrodynamic model using ANSYS Fluent software in order to explore the dispersion phenomenon of pollutant injected at a free surface. The idea was developing a numerical study aimed at tracking the dispersion of pollutant rejected by an industrial waste in a portion of sewer system and then in seawater, taking into account the influence of climatic parameters on the spread of pollutant. Numerical results agree well with the experimental data, and showed that pollutant dispersion is mainly influenced by the presence of vortices and turbulence. Hence, it was observed that the pollution spread in coastal water is strongly correlated with climatic conditions in this region.
