Three-dimensional structure of wind turbine wakes as measured by scanning lidar [PDF]
Atmospheric Measurement Techniques, 2017 The lower wind speeds and increased turbulence that are characteristic of turbine wakes have considerable consequences on large wind farms: turbines located downwind generate less power and experience increased turbulent loads. The structures of wakes

Effects of wind turbine wakes on microclimate properties near the ground [PDF]
, 2021 Archer, Cristina L.Wind energy has been growing steadily in the U.S. and worldwide in the past decades. As wind farms are projected to increase in size and number, however, concerns are rising about possible undesirable effects of wind turbines near the ...

Numerical investigation of wind turbine wakes under high thrust coefficient
Wind Energy, 2022 We study wind turbine wakes of rotors operating at high thrust coefficients (CT > 24/25) using large‐eddy simulations with a rotating actuator disk model. Wind turbine wakes at high thrust coefficients are different from wakes at low thrust coefficients.

Wind turbine wakes for wind energy [PDF]
Wind Energy, 2011 During recent years, wind energy has moved from an emerging technology to a nearly competitive technology. This fact, coupled with an increasing global focus on environmental concern and a political desire of a certain level of diversification in the energy supply, ensures wind energy an important role in the future electricity market.

Study on the Wake of a Miniature Wind Turbine Using the Reynolds Stress Model
Energies, 2016 The Reynolds Stress Model (RSM) is adopted to simulate the wind turbine wake and the simulation results are compared with the wind tunnel test data, simulation results from the standard k-ε model and a modified k-ε model.

Do wind turbines pose roll hazards to light aircraft? [PDF]
Wind Energy Science, 2018 Wind energy accounted for 5.6 % of all electricity generation in the United States in 2016. Much of this development has occurred in rural locations, where open spaces favorable for harnessing wind also serve general aviation airports. As such,

Integrated Design and Experimental Validation of a Fixed-Pitch Rotor for Wind Tunnel Testing
Energies, 2023 In this paper we report about the design and validation of a 1.2 m wind turbine rotor with fixed blade pitch. The wind turbine is a scaled version of the DTU 10 MW. Integrated design of dimensional scaling laws, blade aerodynamics, and turbine control is
