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 …

Vertical axis wind turbines (VAWTs) have received growing interest for off-shore application
and in the urban environments mainly due to their omni-directional capability, scalability …

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 …

Abstract Knowledge of the turbulence in the wakes of wind turbines is important to improve
the operation and lifetime of downstream turbines exposed to these wakes. As the …

A large-eddy simulation (LES) of a laboratory-scale horizontal axis tidal stream turbine
operating over an irregular bathymetry in the form of dunes is performed. The Reynolds …

Wind turbines are usually clustered in wind farms which causes the downstream turbines to
operate in the turbulent wakes of upstream turbines. As turbulence is directly related to …

With the increasing demand for wind energy, it is important to be able to understand and
predict the available wind resources. To that end, the present wind tunnel study addresses …

In this study, we aim to investigate the influence of inflow turbulent length scales on wind
turbine wakes. For this purpose, large-eddy simulations of the wake of a wind turbine are …

Tidal stream turbines deployed at highly energetic open water sites are subjected to
sheared inflow in the rotor plane. The inflow shear is expected to cause asymmetric loading …

Laboratory experiments were carried out to quantify the effect of small-amplitude, passive
oscillations of a model wind turbine in the structure of the unsteady motions, wake statistics …
