Abstract:At the confluence zone, the separation zone affects the flow and pollutant transport, and damages the bed and sidewalls of the channel. In this research, the geometric characteristics of the separation zone and the tailwater effect at the 90° channel–pipe junction are investigated using experiments and numerical simulations. These characteristics are different from the previous study in the channel or river junctions. (1) The separation zone is not attached to the sidewall of the channel. The shape of the sepa… Show more
