Secondary Flow in Sharp Open-channel Bends
TL;DR: The occurrence of the outer-bank cell is shown to be not just due to flow instability, but also to kinetic energy input from turbulence, which shows that turbulence plays a minor role in the generation of the centre-region cell, which is mainly due to the centrifugal force.
Journal ArticleDOI
Mean Flow and Turbulence in Open-Channel Bend
TL;DR: In this article, the cross-sectional motion contains two cells of circulation: besides the classical helical motion (center-region cell), a weaker counterrotating cell (outer-bank cell) is observed in the corner formed by the outer bank and the water surface.
Journal ArticleDOI
Nonlinear modeling of mean flow redistribution in curved open channels
TL;DR: In this paper, a nonlinear closure submodel is proposed to reproduce essential features in moderately to strongly curved flow, where the feedback between the downstream velocity and the secondary circulation is taken into account.
Journal ArticleDOI
Momentum Transport in Sharp Open-Channel Bends
TL;DR: A true quasithree-dimensional flow model is obtained by coupling this nonlinear model to depth-integrated flow models, thus providing an engineering tool for morphodynamical investigations.

TL;DR: In this paper, a conceptual model is proposed for the hydromorpho-sedimentary processes in the Upper Rhone River, and compared to existing conceptual models for confluences with different characteristics, which is characterized by maximum velocities occurring near the bed, and a considerable increase in turbulent kinetic energy generated in the shear layer at the interface of the flows originating from the main channel and the tributary.
