Modelling Yawed Wind Turbine Wakes: Extension of a Gaussian-Based Wake Model [PDF]
Energies, 2021 Yaw-based wake steering control is a potential way to improve wind plant overall performance. For its engineering application, it is crucial to accurately predict the turbine wakes under various yawed conditions within a short time.

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.

Stochastic Wake Modelling Based on POD Analysis [PDF]
Energies, 2018 In this work, large eddy simulation data is analysed to investigate a new stochastic modeling approach for the wake of a wind turbine. The data is generated by the large eddy simulation (LES) model PALM combined with an actuator disk with rotation ...

A non-symmetric Gaussian wake model for lateral wake-to-wake interactions
Journal of Physics: Conference Series, 2023 Abstract In this paper, we propose a new non-symmetric Gaussian wake model, which allows for different lateral expansions on the two sides of a wake to account for its interaction with neighbouring wakes. The proposed model is formulated following classical speed-deficit assumptions and momentum conservation.

Modeling the Wake of the Marquesas Archipelago [PDF]
Journal of Geophysical Research: Oceans, 2018 AbstractIn this study, a high‐resolution (∼2.5 km) numerical model was set up to investigate the fine‐scale activity within the region of the Marquesas archipelago. This has never been performed before. The robustness of the model results is assessed by comparison with remote sensing and in situ observations.

Design and analysis of a wake model for spatially heterogeneous flow [PDF]
Wind Energy Science, 2021 Methods of turbine wake modeling are being developed to more accurately account for spatially variant atmospheric conditions within wind farms. Most current wake modeling utilities are designed to apply a uniform flow field to the entire domain of a wind

A Calibration Procedure for an Analytical Wake Model Using Wind Farm Operational Data
Energies, 2020 Wind energy is one of the fastest growing renewable energy sources in the U.S. Wind turbine wakes change the flow field within wind farms and reduce power generation. Prior research has used experimental and computational methods to investigate and model
