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

Upward Shift of Wind Turbine Wakes in Large Wind Farms [PDF]
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.

Investigation of wind turbine flow and wake [PDF]
Journal of Fluid Science and Technology, 2014 This paper is dedicated to the investigation and analysis of wind turbine wake. An experimental work is undertaken in wind tunnel on a horizontal axis wind turbine model. The velocity field in the wake is measured using PIV with phase synchronization in order to relate velocity and vortices to the rotating blades.

Wind tunnel experiments on wind turbine wakes in yaw: redefining the wake width [PDF]
Wind Energy Science, 2018 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.

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.

A Review on the Meandering of Wind Turbine Wakes [PDF]
Energies, 2019 Meandering describes the large-scale, low frequency motions of wind turbine wakes, which could determine wake recovery rates, impact the loads exerted on turbine structures, and play a critical role in the design and optimal control of wind farms. This paper presents a comprehensive review of previous work related to wake meandering. Emphasis is placed

Replacing wakes with streaks in wind turbine arrays [PDF]
Wind Energy, 2021 Wind turbine wakes negatively affect downwind turbines in wind farms reducing their global efficiency. The reduction of wake‐turbine interactions by actuating control on yaw angles and induction factors is an active area of research.

Modelling wind turbine wakes for wind farms [PDF]
, 2016 The simulation of the wakes behind wind turbines is important in predicting energy yields in wind farms, and so plays a role in planning the layout of these farms. As both wind turbines and farms increase in size, wind farm modellers have faced challenges as previously-held assumptions and parameterisations become inadequate – requiring more detailed ...

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 ...
