Abstract

In high flow velocity areas like those suitable for tidal applications, turbulence intensity is high and flow variations may have a major impact on tidal turbines behaviour. Large boils that can be observed at the sea surface are emitted from the sea floor and may interact with the tidal turbine. These boils have then to be characterized. The Reynolds number,  based on the rugosity height and mean flow velocity, is rather high in this context: Re = 2.5 × 107 . For that purpose, experiments are carried out in a flume tank with Re as high as achievable in Froude similitude (in the tank: Re = 2.5 × 105 and Fr = 0.23) in order to study coherent flow structures emitted behind seabed obstacles. The obstacle is here a canonical square wall-mounted cylinder chosen to be representative of specific in-situ bathymetric variations. Using PIV and LDV measurements, the flow past the cylinder is investigated. The database created is presented in this report.
