Tidal turbines encounter a range of unsteady flow conditions, some of which may induce
severe load fluctuations. Rotor blades can experience stall delay, load hysteresis and …

Understanding the impacts of unsteady flows on tidal turbine performance and loadings
prior to device deployment is essential for mitigating the effects of large hydrodynamic forces …

To achieve the full potential of tidal stream energy, developers are incentivised to use larger
blades on tidal turbines. This requires validation of blade structural designs through full …

To design tidal stream turbine arrays, turbine wakes need to be fully characterized to assess
the adequate row spacing considering environmental factors such as onset turbulence …

Most tidal turbines experimental tests are carried out in idealised conditions with uniform
velocity profiles and without flow misalignment. However, at sea, the velocity profiles are …

In the Marine environment, waves and turbulence usually coexist, affecting the operation
performance of the tidal current energy turbine. This paper conducts experiments on a …

The cost effective design of tidal turbines requires a good estimation of the loading cycles
and their extrema that are related to the unsteady fluctuation of the current velocity. Apart …

Wave measurement buoys provide characterisation of wave climates that forms the basis for
the design of offshore systems. These buoys are commonly subjected to currents which …

This paper investigates the dynamic loading of two side-by-side 1.2 m diameter tidal stream
turbines tested experimentally in currents with regular waves. By towing the turbines through …

Tidal stream turbines (TST) are subject to large unsteady hydrodynamic loads which will
result in fatigue of components and potentially failure. Control algorithms, if used effectively …
