Cross-sectional flow and velocity redistribution in a meandering laboratory flume

2015

The role played by the cross-stream circulation could be important in the longitudinal flow velocity and bed shear stress redistributions, which determine the bed topography (Blanckaert et al., 2008). Recent experimental results obtained in a strongly curved channel (Blanckaert and Graf, 2001) and in a large amplitude meandering flume (Termini and Piraino, 2011) have highlighted that, besides the main central-region cell, a counter-rotating secondary circulation cell forms near the outer bank along the curved reaches of the channel. In this context, the present work aims at improving the understanding of the flow characteristics along a meandering bend. The analysis is based on detailed vel…
