The dynamic coupling between the pulse wake mixing strategy and floating wind turbines [PDF]
Wind Energy Science, 2023 In recent years, control techniques such as dynamic induction control (often referred to as “the pulse”) have shown great potential in increasing wake mixing, with the goal of minimising turbine-to-turbine interaction within a wind farm.

Wind Turbine Wakes in Directionally Varying Wind Shears [PDF]
, 2019 In the atmospheric boundary layer, the Coriolis force associated with the Earth’s rotation induces a spanwise wind shear in addition to the wall-normal one leading to a continuous change in wind direction with height. The spanwise wind shear in directionally sheared inflow has a significant impact on the formation and development of wind-turbine wakes.

Stability of Floating Wind Turbine Wakes
Journal of Physics: Conference Series, 2021 Abstract Floating offshore wind turbines (FOWTs) are the next frontier in offshore wind energy, allowing exploration of deep-water regions previously unavailable to fixed-foundation turbines. Since offshore turbines operate in lower turbulence levels, the intrinsic hydrodynamic unstable modes of the tip vortices can have even more ...

Aeroelastic load validation in wake conditions using nacelle-mounted lidar measurements [PDF]
Wind Energy Science, 2020 We propose a method for carrying out wind turbine load validation in wake conditions using measurements from forward-looking nacelle lidars. Two lidars, a pulsed- and a continuous-wave system, were installed on the nacelle of a 2.3 MW wind turbine

Measurement procedures for characterization of wind turbine wakes with scanning Doppler wind LiDARs [PDF]
Advances in Science and Research, 2013 The wake flow produced from an Enercon E-70 wind turbine is investigated through three scanning Doppler wind LiDARs. One LiDAR is deployed upwind to characterize the incoming wind, while the other two LiDARs are located downstream to carry out wake ...

Lidar-based wake tracking for closed-loop wind farm control [PDF]
, 2017 This work presents two advancements towards closed-loop wake redirection of a wind turbine. First, a model-based wake-tracking approach is presented, which uses a nacelle-based lidar system facing downwind to obtain information about the wake. The method
