Abstract: The Lagrangian second-moment method is used to compute the dye-concentration distribution in turbulent recirculating flow generated in a shallow open channel by a sudden widening of flow in the transverse direction. The ...

Abstract: Tracer studies were performed at the full-scale St-Hermas aerated lagoon, Quebec, Canada, and a dynamically similar laboratory model to determine the effects of the water flow rate and aeration rate on hydraulic mixing. ...

Abstract: Dye‐concentration measurements are conducted in the recirculating region of a sudden open‐channel‐flow expansion, where the water depth is shallow compared with the horizontal length scale of the channel expansion. The ...

Abstract: Numerical computations are conducted of the flow across a turbulent mixing layer in an open channel of small depth using three turbulence models: a single-length-scale model, a modified single-length-scale model, and a ...

Abstract: Experiments were conducted to study the bed‐friction influence in the recirculating zone of a shallow open‐channel flow. Velocity measurements were made using a hot‐film anemometer. The recirculating flow rate and the ...

Abstract: The recirculating flow produced by a sudden widening of flow in a shallow open channel is computed using three turbulence models including (1) a constant-eddy-viscosity model; (2) a depth-averaged
