Abstract

In presence of suction or injection, the process of dispersion of solute in an open channel flow is investigated through this work. The dispersion coefficient is analytically determined by using Mei’s multi-scale analysis approach up to second order. The effect of suction or injection on dispersion coefficient are displayed graphically and discussed. The novelty of the present research is to find the effect of suction/injection Reynolds number on the dispersion coefficient and concentration distribution of the solute. It is found that the mass dispersivity decreases with the increment of suction/injection Reynolds number. The present study may play a significant role in the process of wastewater treatment. It is observed that, as dispersion time progresses, the amplitude of the concentration curves along longitudinal direction becomes flat. It is observed that the iso-concentration contour spreads along the longitudinal direction with the enhancement of injection Reynolds number.
