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 turbulent structures are present in the water column and may interact with the tidal turbine. The Reynolds number, based on the rugosity height and mean flow velocity, is rather high in this context: Re=2.5x107. For that purpose, experiments are carried out in a flume tank with Re as high as achievable in Froude similitude (in the tank: Re=2.5x105 and Fr=0.23) in order to study the wake past seabed obstacles. The obstacle is here a canonical square wall-mounted cube chosen to be representative of specific in-situ bathymetric variations. To represent the variability of turbulent in-situ conditions, different upstream turbulence rate are achieved. Using PIV and LDV measurements, the flow past the cube is investigated. The experimental database is presented in this report.
