Evaluating Mechanical Strength in Vertical-Axis Tidal Turbines: A Comparative Study of Internal Blade Structure and Material Selection through CFD Simulation [PDF]

E3S Web of Conferences
Due to the density of water, tidal turbine blades are subject to significantly greater stresses than wind turbine blades. Multiple blade failures occurred during prototype testing as a result of loading conditions and protracted exposure to seawater ...

Review of tidal turbine wake modelling methods

International Marine Energy Journal, 2020
Enabling Future Arrays in Tidal (EnFAIT) is an EU Horizon 2020 flagship tidal energy project. It aims to demonstrate the development, operation and decommissioning of the world’s largest tidal array (six turbines), over a five-year period, to prove a ...

Impaired nitric oxide‐dependent endothelial function in young male individuals with obesity before the onset of symptoms and complications

Experimental Physiology, Volume 111, Issue 3, Page 1134-1149, 1 March 2026.
Abstract Endothelial dysfunction drives obesity‐related complications. Doppler ultrasound measurement of blood flow during 1‐min passive leg movements (PLM) is a valuable non‐invasive tool for assessing endothelial function and nitric oxide (NO)‐mediated vasodilation.

An optimal tuning strategy for tidal turbines [PDF]

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2016
Tuning wind and tidal turbines is critical to maximizing their power output. Adopting a wind turbine tuning strategy of maximizing the output at any given time is shown to be an extremely poor strategy for large arrays of tidal turbines in channels. This ‘impatient-tuning strategy’ results in far lower power output, much higher structural loads and ...

Breathing technique‐dependent acute cardiopulmonary responses during squats in healthy females

Physiological Reports, Volume 14, Issue 6, March 2026.
Abstract Breath‐holding (BH), including variations of the Valsalva maneuver, is used during resistance exercise to stabilize the trunk and increase intra‐abdominal pressure. However, its hemodynamic and ventilatory effects during low‐to‐moderate intensity strength training in women remain unclear.

Ocean Energy: Using the Ocean's Tides, Waves, and Heat to Generate Electricity [PDF]

, 2006
Key facts: - The oceans' tides, waves, current, and heat can be used to generate electricity. These resources are renewable, because the moon's gravity drives tides, and winds create waves.

Generator Systems for Marine Current Turbine Applications: A Comparative Study [PDF]

, 2014
Emerging technologies for marine current turbines are mainly related to works that have been carried out on wind turbines and ship propellers. It is then obvious that many electric generator topologies could be used for marine current turbines. As in the

Chapter Tidal Turbine Generators

, 2020
Recently, tidal stream turbines have become a preferable mode of harvesting tidal energy. The main issue for low utilization of tidal energy is the high levelized cost of energy (LCoE) from tidal stream turbines. A major reason for this is the high operation and maintenance costs for submerged installations.

Evaluating the Risk of Collision of Seals Swimming Within Metres of Operating Tidal Turbines

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT We used imaging sonar to continuously monitor wildlife at an operational tidal turbine in the Pentland Firth, Scotland, between May 2022 and June 2023. Of 704 detected seal tracks, 347 occurred during turbine operation and 122 of these were detected directly upstream of the rotating blades in the horizontal plane.
