The ocean contains a variety of renewable energy resources, little of which has been
exploited. Here, we review both tidal range and tidal stream energy, with a focus on the …

The tides are a predictable, renewable, source of energy that, if harnessed, can provide
significant levels of electricity generation. The Alderney Race (AR), with current speeds that …

A counter-rotating tidal turbine can balance the axial torque and accelerate the wake
recovery, leading to a more conducive array layout. This paper aims to investigate the …

Array research of tidal turbine is critical to make it cost-effective and commercializing. There
are many studies of turbine arrays, which mostly focus on a conventional horizontal-axis …

Ocean energy extraction is on the rise. While tides are the most predictable amongst marine
renewable resources, turbulent and complex flows still challenge reliable tidal stream …

A system of two coupled four-beam acoustic Doppler current profilers was used to collect
turbulence measurements over a 36-h period at a highly energetic tidal energy site in …

Velocity fluctuations caused by unsteady flows substantially increase mechanical loads on
tidal turbine blades and represent a major challenge to tidal energy converters. Overcoming …

Highly energetic turbulent flow structures are observed in strong tidal flows. If they are
suspected to result from interactions between the flow and the seabed morphology, the …

The upcoming commercial development of tidal stream power requires a profound
knowledge of tidal streams. In this article, the spatial and temporal variations of the flow …

The increased turbulence behind the turbine induces a fatigue load on the downstream
turbine blades. An accurate estimate of turbulent intensity in turbine wake is paramount to …
