Re-Creating Waves in Large Currents for Tidal Energy Applications [PDF]
Energies, 2017 Unsteady wave loading on tidal turbines impacts significantly the design, and expected life-time, of turbine blades and other key components. Model-scale testing of tidal turbines in the wave-current environment can provide vital understanding by emulating real-world load cases; however, to reduce uncertainty, it is important to isolate laboratory ...

Modelling effects of tidal currents on waves at a tidal stream energy site [PDF]
Renewable Energy, 2017 Whereas tidal stream energy sites may be characterised by significant wave and current interactions, numerical resource assessments routinely ignored these processes neglecting, in particular, current-induced modifications of waves. Here, these effects are investigated in locations exposed to ocean waves, evaluating performances of a phase-averaged ...
