Analysis of Wind Power Fluctuation in Wind Turbine Wakes Using Scale-Adaptive Large Eddy Simulation
WindIn large wind farms, the interaction of atmospheric turbulence and wind turbine wakes leads to complex vortex dynamics and energy dissipation, resulting in reduced wind velocity and subsequent loss of wind power.

Analytical model for the power–yaw sensitivity of wind turbines operating in full wake [PDF]
Wind Energy Science, 2020 Wind turbines are designed to align themselves with the incoming wind direction. However, turbines often experience unintentional yaw misalignment, which can significantly reduce the power production.

Analysis and validation of CFD wind farm models in complex terrain. Effects induced by topography and wind turbines [PDF]
, 2010 Wind farms have been extensively simulated through engineering models for the estimation of wind speed and power deficits inside wind farms. These models were designed initially for a few wind turbines located in flat terrain.

Towards Identifying Contribution of Wake Turbulence to Inflow Noise from Wind Turbines
E3S Web of Conferences, 2015 Downstream turbines in a wind farm often operate under the influence of wakes from upstream turbines. Aerodynamic losses and aeromechanical issues (stochastic loads) associated with such wake-turbine interactions have been investigated before.

Fish schooling as a basis for vertical axis wind turbine farm design [PDF]
, 2000 Most wind farms consist of horizontal axis wind turbines (HAWTs) due to the high power coefficient (mechanical power output divided by the power of the free-stream air through the turbine cross-sectional area) of an isolated turbine.

Power and Flow Analysis of Axial Induction Control in an Array of Model-Scale Wind Turbines
Energies, 2022 As research on wind energy has progressed, it has broadened from a focus on the wind turbine to include the entire wind farm. In particular, methods to mitigate the negative effects of upstream wakes on downstream turbines have received significant ...

Towards a Simplified Dynamic Wake Model using POD Analysis [PDF]
, 2015 We apply the proper orthogonal decomposition (POD) to large eddy simulation data of a wind turbine wake in a turbulent atmospheric boundary layer. The turbine is modeled as an actuator disk. Our analyis mainly focuses on the question whether POD could be
