3D simulation on 90 degree off-take branching channel with separation zones

Flow separation occurs often in river diversion, particularly in branch channels. The flow separation is generally seen through its separation area, which is influenced by a number of factors such as off-take angles, discharge ratios, and channel widths. The study was conducted through computational...
