Physical Modelling of Tidal Stream Turbine Wake Structures under Yaw Conditions
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 ...

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 ...

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 ...
