Optimized design of tidal current turbine blade at low current rate
Proceedings of Global Power & Propulsion Society, 2023 Blades have a significant influence on a tidal current turbine (TCT)’s energy transfer capacity. In order to ensure a blade working safely and efficiently in low flow rates, a special design is needed. Hydrofoil’s shape and blade’s quality are the key factors which affect blade’s dynamic and starting performance at low flow rate.

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.
