The Importance of Wake Meandering on Wind Turbine Fatigue Loads in Wake [PDF]
Energies, 2021 Considering loads when optimizing wind-farm layouts or designing farm-control strategies is important, but the computational cost of using high-fidelity wake models in the loop can be prohibitively high. Using simpler models that consider only the spatial variation of turbulence statistics is a tempting alternative, but the accuracy of these models ...

Multirotor wind turbine wakes [PDF]
Physics of Fluids, 2019 To fulfill the increasing need for large power generation by wind turbines, the concept of multirotor wind turbines has recently received attention as a promising alternative to conventional massive single-rotor wind turbines. To shed light on the viability of this concept, large-eddy simulation is employed in this study to compare wake flow properties

The stability of wakes of floating wind turbines
Physics of Fluids, 2022 Floating offshore wind turbines (FOWTs) are subjected to platform motion induced by wind and wave loads. The oscillatory movement trigger vortex instabilities, modifying the wake structure and influencing the flow reaching downstream wind turbines. In this work, the wake of a FOWT is analyzed by means of numerical simulations and a comparison with ...

Upward Shift of Wind Turbine Wakes in Large Wind Farms
Energies, 2023 A detailed description of wake characteristics is essential for optimizing wind farm performance. Compared with the wake of a stand-alone wind turbine, less attention has been paid to wind turbine wakes in large wind farms.

Wind tunnel experiments on wind turbine wakes in yaw: Redefining the wake width [PDF]
Wind Energy Science, 2018 Abstract. This paper presents an investigation of wakes behind model wind turbines, including cases of yaw misalignment. Two different turbines were used and their wakes are compared, isolating effects of boundary conditions and turbine specifications. Laser Doppler Anemometry was used to scan a full plane of a wake normal to the main fow direction, 6 ...
