Extracting power from the tide is a potential avenue for renewable energy production but is
also a significant engineering challenge. This challenge has many different aspects but the …

Recently, the output of Computational Fluid Dynamic (CFD) prediction on tidal stream
turbine systems has been receiving great attention owing to the vast and untapped tidal …

Laboratory scale testing of tidal turbines has generated valuable datasets to support
optimised turbine design and numerical model validation. However, tidal sites are highly …

Turbulence and waves interactions are present in tidal streams ensuing the poorly
comprehended unsteady state. To clarify several aspects of the wave influence on the flow …

A coupled blade element momentum–computational fluid dynamics (BEM–CFD) model is
used to conduct simulations of groups of tidal stream turbines. Simulations of single, double …

The results of a detailed experimental investigation of the near-wake (up to seven turbine
diameters downstream) of a model horizontal axis tidal turbine (HATT) device in a large …

Power-to-gas to energy systems are of increasing interest for low carbon fuels production
and as a low-cost grid-balancing solution for renewables penetration. However, such gas …

Aspect Ratio (AR) is one of the main design parameters of straight-bladed vertical axis
turbines. This paper will examine whether a high AR, with long blades and low tip losses, or …

Until recently tidal stream turbine design has been carried out mainly by experimental
prototype testing aiming at maximum turbine efficiency. The harsh and highly turbulent …

Abstract With many Tidal Energy Conversion (TEC) devices at full scale prototype stage
there are two distinct design groups for Horizontal Axis Tidal Turbines (HATTs). Devices with …
