Physical Modelling of Tidal Stream Turbine Wake Structures under Yaw Conditions [PDF]
Energies, 2023 Tidal stream turbines may operate under yawed conditions due to variability in ocean current directions. Insight into the wake structure of yawed turbines can be essential to ensure efficient tidal stream energy extraction, especially for turbine arrays ...

Analysis of the kinetic energy recovery behind a tidal stream turbine for various submergence levels
International Marine Energy Journal, 2022 Tidal turbines are commonly deployed at sea sites with water depths of up to 50 m to ease their deployment and quick maintenance operations. In these relatively shallow water depth conditions, the vertical expansion of tidal stream turbine wakes is ...

Flow-controlled expiration improves gas exchange in anaesthetised horses undergoing orthopaedic surgery. [PDF]
Equine Vet JAbstract Background Flow‐controlled expiration (FLEX) has been shown to significantly enhance oxygenation in horses under laboratory conditions. Objective This study aims to corroborate these findings by evaluating the effects of FLEX on gas exchange in a randomised clinical trial involving a large population of clinical horses undergoing orthopaedic ...

Reliability of tidal stream turbine blades
, 2011 Tidal stream turbines are a new technology for extracting kinetic energy from tidal currents. A number of different concepts of such devices have been proposed up to now and the most popular of them is a horizontal-axis turbine with propeller-type blades.

Tidal Turbines’ Layout in a Stream with Asymmetry and Misalignment [PDF]
Energies, 2017 A refined assessment of tidal currents variability is a prerequisite for successful turbine deployment in the marine environment. However, the numerical evaluation of the tidal kinetic energy resource relies, most of the time, on integrated parameters ...
