On tidal stream turbines placed off headlands [PDF]
Journal of Renewable and Sustainable Energy, 2015 Many candidate sites for tidal stream energy extraction can be classified as headland sites. Understanding the tidal resource of such sites is of fundamental importance to the industry. This paper examines an upper bound for the power that might be generated from an idealised headland. The dependence of this on length of turbine rows, number of turbine

Energy Science &Engineering, EarlyView.This paper aims to provide a robust design approach for HAWTs operating in shear flow. This study fills a critical research gap by integrating BEM and vortex theories for blade design in non‐homogeneous inflow conditions. The authors of the paper made an effort to develop and test an experimentally unsophisticated model of a turbine working in shear ...

Surrogate-based optimization of tidal turbine arrays: a case study for the Faro-Olhão inlet [PDF]
, 2019 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

Modelling impacts of tidal stream turbines on surface waves [PDF]
Renewable Energy, 2019 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.

The impact of diffuser augmentation on a tidal stream turbine [PDF]
Ocean Engineering, 2015 AbstractThe results from an experimental study of a model diffuser augmented tidal stream turbine are presented with a particular focus on the impact of the diffuser upon the turbine׳s performance in yawed flows. This study is the first to examine yaw effects with quantification of blockage corrections and is the first study of the wake recovery ...
