Evaluation of Free-Surface Exposure Effects on Tidal Turbine Performance Using CFD
Journal of Marine Science and EngineeringTidal turbines represent a promising renewable energy source, generating power from ocean currents. However, due to tidal range variations, they sometimes become partially exposed to the free surface.

, 2016 Computational fluid dynamics (CFD) is used in this thesis to model wind and tidal stream turbines and to investigate tidal turbine fence performance. There are two primary objectives of this work. The first is to develop and validate an actuator line method for the simulation of wind and tidal turbines which applies the blade forces to the flow field ...

Large Eddy Simulation Of Tidal Turbines
, 2017 Understanding of hydrodynamics involved in the ow around tidal turbines is essential to enhance their performance and resilience, as they are designed to operate in harsh marine environments. During their lifespan, they are subjected to high velocities with large levels of turbulence that demand their design to be greatly optimised.

Spanwise flow corrections for tidal turbines
International Marine Energy Journal, 2018 Actuator line computations of two different tidal turbine rotor designs are presented over a range of tip speed ratios. To account for the reduction in blade loading on the outboard sections of these rotor designs, a spanwise flow correction is applied ...

, 2009 Tidal turbines offer an exciting opportunity to exploit ocean current flows to generate sustainable energy. However, a key to their success is the ability to operate with minimal intervention in the ocean over extended periods (15-20 years). This talk explored the likely design and operational issues that will influence satisfactory performance ...

Design of a Horizontal Axis Tidal Turbine for Less Energetic Current Velocity Profiles
Journal of Marine Science and Engineering, 2019 Existing installations of tidal-stream turbines are undertaken in energetic sites with flow speeds greater than 2 m/s. Sites with lower velocities will produce far less power and may not be as economically viable when using “conventional” ...
