DOI: 10.1016/j.apenergy.2021.116729
Abstract: Abstract The presence of the wind-waves enhances the flow turbulent complexity and modifies the dynamic behaviour of the tidal-stream turbine and causes extra challenges for its performance and survivability. A sign of these effects is… read more here.

DOI: 10.1016/j.energy.2019.06.181
Abstract: Abstract Temporal variability in renewable energy presents a major challenge for electrical grid systems. Tides are considered predictable due to their regular periodicity; however, the persistence and quality of tidal-stream generated electricity is unknown. This… read more here.
