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: The shore attachment of buoyant effluent in a strong crossflow is investigated experimentally. The effluent, in the form of a thermal plume deflected by the crossflow, is created in the laboratory by discharging warm water ...

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: Shallow turbulent flows were produced in a tank of small thickness to study the friction effects on large-scale turbulent motion of small depth. The tank was constructed of two parallel walls. The space between the parallel ...

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

Abstract: The present study deals with the noninvasive measurement of concentration in the intermediate shallow turbulent wake region using a video-imaging technique. The flow depths considered in the ...

Abstract: The scalar concentration and velocity field of an axisymmetric turbulent jet in a coflow are measured using laser-induced fluorescence and laser Doppler anemometry techniques. Both the time-averaged and turbulence data ...

Abstract: The bed‐friction effect on the stability of transverse shear flows in shallow open channels is examined using a linear and “inviscid” theory. Numerical calculations are conducted for four groups of parallel flows with ...
