Study on Actuator Line Modeling of Two NREL 5-MW Wind Turbine Wakes [PDF]
Applied Sciences (Switzerland), 2018 The wind turbine wakes impact the efficiency and lifespan of the wind farm. Therefore, to improve the wind plant performance, research on wind plant control is essential. The actuator line model (ALM) is proposed to simulate the wind turbine efficiently.

Atmospheric Turbulence Effects on Wind-Turbine Wakes: An LES Study
Energies, 2012 A numerical study of atmospheric turbulence effects on wind-turbine wakes is presented. Large-eddy simulations of neutrally-stratified atmospheric boundary layer flows through stand-alone wind turbines were performed over homogeneous flat surfaces with ...

The Jensen wind farm parameterization [PDF]
Wind Energy Science, 2022 Wind farm power production is known to be significantly affected by turbine wakes. When mesoscale numerical models are used to predict power production, the turbine wakes cannot be resolved directly because they are sub-grid features, and therefore their

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.

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
