Modelling Yawed Wind Turbine Wakes: Extension of a Gaussian-Based Wake Model [PDF]

open access: yesEnergies, 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.

Stochastic Wake Modelling Based on POD Analysis [PDF]

open access: yesEnergies, 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 ...

Dynamic wake meandering modeling [PDF]

open access: yes, 2007
We present a consistent, physically based theory for the wake meandering phenomenon, which we consider of crucial importance for the overall description of wind turbine loadings in wind farms. In its present version the model is confined to single wake situations.

Wake modeling and simulation [PDF]

open access: yes, 2008
We present a consistent, physically based theory for the wake meandering phenomenon, which we consider of crucial importance for the overall description of wind turbine loadings in wind farms. In its present version the model is confined to single wake situations.

A non-symmetric Gaussian wake model for lateral wake-to-wake interactions

open access: yesJournal 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.

Joukowski’s wake model for tip-splitting rotors [PDF]

open access: yesJournal of Physics: Conference Series, 2021
Abstract The interaction between a tip vortex and a solid surface is responsible for premature structural component fatigue in wind turbines and undesirable noise in helicopter rotors during low speed and descending flight. One noise reduction strategy uses a modified airfoil to split and spread the vorticity in two tip vortices.

Design and analysis of a wake model for spatially heterogeneous flow [PDF]

open access: yesWind 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

open access: yesEnergies, 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
