Validation of an interpretable data-driven wake model using lidar measurements from a field wake steering experiment [PDF]
Wind Energy Science, 2023 Data-driven wake models have recently shown a high accuracy in reproducing wake characteristics from numerical data sets. This study used wake measurements from a lidar-equipped commercial wind turbine and inflow measurements from a nearby meteorological

A physically interpretable data-driven surrogate model for wake steering [PDF]
Wind Energy Science, 2022 Wake steering models for control purposes are typically based on analytical wake descriptions tuned to match experimental or numerical data. This study explores whether a data-driven surrogate model with a high degree of physical interpretation can ...

A New Streamwise Scaling for Wind Turbine Wake Modeling in the Atmospheric Boundary Layer
Energies, 2022 In this study, we aim to investigate if there is a scaling of the streamwise distance from a wind turbine that leads to a collapse of the mean wake velocity deficit under different ambient turbulence levels.

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.

Application of the Townsend–George theory for free shear flows to single and double wind turbine wakes – a wind tunnel study [PDF]
Wind Energy Science, 2022 The evolution of the mean velocity and the turbulence downstream of wind turbine wakes within the atmospheric boundary layer has been studied over the past decades, but an analytical description is still missing.

Lidar measurements of yawed-wind-turbine wakes: characterization and validation of analytical models [PDF]
Wind Energy Science, 2020 Wake measurements of a scanning Doppler lidar mounted on the nacelle of a full-scale wind turbine during a wake-steering experiment were used for the characterization of the wake flow, the evaluation of the wake-steering set-up, and the validation of ...

Towards higher accuracy in wind farm deficit decay modelling – a comparison
Meteorologische Zeitschrift, 2023 Wind farm wake behaviour and forecasting is gaining the importance recently. It is especially relevant in the German Bight where space for wind farm clusters is limited, and wind farm wake lengths of up to 60 km have been measured.

A linear wake expansion function for the double‐Gaussian analytical wake model
Energy Science & Engineering, 2023 The double‐Gaussian (DG) approach for analytical wake modeling leads to a better understanding of the wake transition mechanism within a full‐wake region behind a non‐yawed horizontal‐axis wind turbine (HAWT).
