Physical Modelling of Tidal Stream Turbine Wake Structures under Yaw Conditions

Energies, 2023
Tidal stream turbines may operate under yawed conditions due to variability in ocean current directions. Insight into the wake structure of yawed turbines can be essential to ensure efficient tidal stream energy extraction, especially for turbine arrays ...

Surface Characterisation of Kolk-Boils within Tidal Stream Environments Using UAV Imagery

Journal of Marine Science and Engineering, 2021
High-flow tidal stream environments, targeted for tidal turbine installations, exhibit turbulent features, at fine spatio-temporal scales (metres and seconds), created by site-specific topography and bathymetry. Bed-derived turbulent features (kolk-boils)

Modeling Evaluation of Tidal Stream Energy and the Impacts of Energy Extraction on Hydrodynamics in the Taiwan Strait

Energies, 2013
Tidal stream speeds in straits are accelerated because of geographic and bathymetric features. For instance, narrow channels and shallows can cause high tidal stream energy.

An Experimental Study on the Darrieus-Savonius Turbine for the Tidal Current Power Generation

Journal of Fluid Science and Technology, 2008
The Darrieus turbine is popular for tidal current power generation in Japan. It is simple in structure with straight wings rotating around a vertical axis, so that it has no directionality against the motion of tidal flow which changes its direction ...
