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

Optimal tuning of engineering wake models through lidar measurements [PDF]
Wind Energy Science, 2020 Engineering wake models provide the invaluable advantage to predict wind turbine wakes, power capture, and, in turn, annual energy production for an entire wind farm with very low computational costs compared to higher-fidelity numerical tools.

Journal of Physics: Conference Series, 2015 A team of researchers from the National Renewable Energy Laboratory and Statoil used large-eddy simulations to numerically investigate the merging wakes from upstream offshore wind turbines. Merging wakes are typical phenomena in wind farm flows in which neighboring turbine wakes consolidate to form complex flow patterns that are as yet not well ...

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.

Generalized coupled wake boundary layer model: applications and comparisons with field and LES data for two wind-farms [PDF]
, 2016 We describe a generalization of the Coupled Wake Boundary Layer (CWBL) model for wind-farms that can be used to evaluate the performance of wind-farms under arbitrary wind inflow directions whereas the original CWBL model (Stevens et al., J.

Replacing wakes with streaks in wind turbine arrays
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.

Bidirectional wakes over complex terrain using SCADA data and wake models [PDF]
Wind Energy ScienceWe investigate bidirectional wake effects between two wind turbines of the same type in a hill region in northern Japan using supervisory control and data acquisition (SCADA) data and validate the simulated wakes using 12 wake models. The extent to which

Wake properties and power output of very large wind farms for different meteorological conditions and turbine spacings: a large-eddy simulation case study for the German Bight [PDF]
Wind Energy Science, 2022 Germany's expansion target for offshore wind power capacity of 40 GW by the year 2040 can only be reached if large portions of the Exclusive Economic Zone in the German Bight are equipped with wind farms.

Simulation of wind turbine wake interaction using the vorticity transport model [PDF]
, 2010 The aerodynamic interactions that can occur within a wind farm can result in the constituent turbines generating a lower power output than would be possible if each of the turbines were operated in isolation.

3-D shear-layer model for the simulation of multiple wind turbine wakes: description and first assessment [PDF]
Wind Energy Science, 2017 The number of turbines installed in offshore wind farms has strongly increased in the last years and at the same time the need for more precise estimations of the wind farm efficiency too.
