Abstract: In the mixing layer at the interface between an open-channel flow and its adjacent lateral open-channel cavity, vortices are periodically shed and advected towards the downstream corner. As these vortices impinge the ...

Abstract: The primary challenge for river managers in handling open-channel bifurcations is the prediction of the discharge distribution to downstream branches. In this study, we aimed to summarize and complete the available database ...

Abstract: This paper describes the flow structures that occur in a 90° junction of four open channels with supercritical flow in two orthogonal inlet channels. An experimental facility was constructed to permit the measurement of ...

Abstract: Intense rainfall on urban areas can generate severe flooding in the city, and if the conditions are right, the flow in the streets can be supercritical. The redistribution of the flow in street intersections determines the ...

Abstract: High-return-period floods involve complex flows over large floodplains covered with different types of resistive elements, from bed roughness to large emerging obstacles. In order to characterize the flow resistance in ...

Abstract: The drag reduction method using polymer additives is a common strategy to minimize friction losses when carrying fluids (water, oil, or slurries) in pipes over long distances. Previous studies showed that the interactions ...

Abstract: The motivation for the present work comes from the fact that a few recent publications describing separation flows report a counter-gradient diffusion phenomenon (CDP) along the separating streamline. This CDP is related ...
