Validation of tidal turbine wake simulations using an open regional-scale 3D model against 1MW machine and site measurements

Ocean Engineering
Full-scale tidal turbines deployed in tidal channels are subjected to complex flow due to the effects of local bathymetry and coastline shape which modify the flow directionality, shear, twist and speed of the underlying tidally forced flow.

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

Biological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

On the impact of waves and turbulence on the power fluctuations and wake structure of a tidal-stream turbine

The Physics of Fluids, 2023
Anticipating the power output of tidal-stream turbines (TSTs) is relevant for its technological advance and success. Therefore, it is important to clarify the behavior of TSTs under tidal-stream environments, which include both waves and currents.
