Surrogate-based optimization of tidal turbine arrays: a case study for the Faro-Olhão inlet [PDF]
This paper presents a study for estimating the size of a tidal turbine array for the Faro-Olhão Inlet (Potugal) using a surrogate optimization approach. The method compromises problem formulation, hydro-morphodynamic modelling, surrogate construction and

Unsteady Hydrodynamics of Tidal Stream Turbines
The unsteady hydrodynamics of tidal stream turbines have been investigated using numerical methods and experiments. Dynamic inflow, which represents the change in backflow induced by the circulation present in the wake due to variations in rotor loading, is the particular focus of this work.

Response‐Based Prediction of Tidal Currents
Abstract This study evaluates the response method for predicting tidal currents. We introduce a coupled response model which explicitly accounts for interactions between velocity components. By leveraging non‐parametric and data‐driven weight estimation, the approach demonstrates superior predictive accuracy compared to classical harmonic analysis (HA),

Economic analysis of tidal stream turbine arrays: a review
This tidal stream energy industry has to date been comprised of small demonstrator projects made up of one to a four turbines. However, there are currently plans to expand to commercially sized projects with tens of turbines or more. As the industry moves to large-scale arrays for the first time, there has been a push to develop tools to optimise the ...

Modelling impacts of tidal stream turbines on surface waves [PDF]
Abstract A high resolution Computational Flow Dynamics (CFD) numerical model is built based on a laboratory experiment in this research to study impacts of tidal turbines on surface wave dynamics. A reduction of ∼ 3 % in wave height is observed under the influence of a standalone turbine located 0.4 m from the free surface.
