Tidal Current Turbine Wake and Park Layout in Transient Environments [PDF]
Volume 9B: Ocean Renewable Energy, 2014 Due to orbital velocities of the waves, the characteristics of tidal current turbines change over time. Therefore the induction factor and subsequent the wake is time dependent. Within the present research this time dependency is investigated by using Computational Fluid Dynamics (CFD) with Virtual Free Surface (VFS) and Actuator Disc (ACD) models.

Coupled Interactions Analysis of a Floating Tidal Current Power Station in Uniform Flow
Journal of Marine Science and Engineering, 2021 For a floating tidal current power station moored in the sea, the mutual interactions between the carrier and the turbine are pretty complex. Current simulation methods based on potential flow theory could not consider the complicated viscous effects ...

An unsteady hydrodynamic model for tidal current turbines [PDF]
, 2014 Due to concerns about the impacts of carbon emissions on the environment, the security of supply of electricity and the likelihood of achieving “peak-oil” in the near future, governments have legislated to reduce reliance on fossil fuels. An attractive alternative is power obtained from tidal currents, and the coast of the British Isles is especially ...

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)

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 ...

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 ...
