A Numerical Study of Steady Transport Model in Turbulent Flow from a Point Source

In this study, the dispersion of some substance in a river with turbulent flow is considered. In this case, the effect of three factors consist of length, width, and flow velocity on substance dispersion is investigated. The dispersion problem is modeled using diffusion-convection equation. Since the problem may not be solved analytically, a numerical method is chosen, namely the Dual Reciprocity Method (DRM). Numerical solutions are presented to describe the effect of the three factors on the distribution of the substance in the turbulent water flow.
