Improving tidal turbine array performance through the optimisation of layout and yaw angles

International Marine Energy Journal, 2022
Tidal stream currents change in magnitude and direction during flood and ebb tides. Setting the most appropriate yaw angles for a tidal turbine is not only important to account for the performance of a single turbine, but can also be significant for the

Performance and Condition Monitoring of Tidal Stream Turbines [PDF]

PHM Society European Conference, 2014
Research within the Cardiff Marine Energy Research Group (CMERG) has considered the integrated mathematical modelling of Tidal Stream Turbines (TST). The modelling studies are briefly reviewed. This paper concentrates on the experimental validation testing of small TST models in a water flume facility.

ACTUATOR-LINE CFD MODELLING OF TIDAL-STREAM TURBINES [PDF]

Journal of Ocean Engineering and Marine Energy, 2016
CFD modelling of tidal turbines is described. For computational efficiency rotors are represented by rotating actuator lines and nacelles by partially-blocked cells. The computational implementation includes an arbitrary Lagrangian-Eulerian (ALE) approach to free-surface movement for wave motion.

Experimental Analysis and Evaluation of the Numerical Prediction of Wake Characteristics of Tidal Stream Turbine

Energies, 2017
It is important to understand tidal stream turbine performance and flow field, if tidal energy is to advance. The operating condition of a tidal stream turbine with a supporting structure has a significant impact on its performance and wake recovery. The

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.

The influence of waves on morphodynamic impacts of energy extraction at a tidal stream turbine site in the Pentland Firth [PDF]

, 2018
Extraction of energy from tidal streams has the potential to impact on the morphodynamics of areas such as sub-tidal sandbanks via alteration of hydrodynamics. Marine sediment transport is forced by both wave and tidal currents. Past work on tidal stream
