Experiments in the wind turbine far wake for the evaluation of an analytical wake model
Journal of Physics: Conference Series, 2017 Nowadays, not only the size of single wind turbines but also the size of wind farms is increasing. Understanding the interaction between the turbines and especially the wakes formed behind them are getting more important to further improve such wind turbine arrays. Consequently, new issues in wind energy research arise.

A physical wind‐turbine wake growth model under different stratified atmospheric conditions
Wind Energy, 2022 The wind‐turbine wake growth is crucial for wake assessment. At present, it can only be determined empirically, which is the primary source of prediction errors in the analytical wake model, and a physically‐based method is urgently needed. Recently, the

Analytical Modeling for Prediction of Horizontal-Axis Wind Turbines Power Generation in Wind Farms Based on an Analytical Wake Model [PDF]
Iranica Journal of Energy and Environment, 2022 The development of models that predict power production of wind farms (WFs) by considering the interacting wakes is important; because wakes of the turbines exert a significant influence on power production of turbines, and hence on the layout of wind ...

An analytical model for a full wind turbine wake
Journal of Physics: Conference Series, 2016 An analytical wind turbine wake model is proposed to predict the wind velocity distribution for all distances downwind of a wind turbine, including the near-wake. This wake model augments the Jensen model and subsequent derivations thereof, and is a direct generalization of that recently proposed by Bastankhah and Porte-Agel.

Analytical Modeling of Wind Farms: A New Approach for Power Prediction
Energies, 2016 Wind farm power production is known to be strongly affected by turbine wake effects. The purpose of this study is to develop and test a new analytical model for the prediction of wind turbine wakes and the associated power losses in wind farms.

Breakdown of the velocity and turbulence in the wake of a wind turbine – Part 2: Analytical modeling
Wind Energy Science, 2022 Abstract. This work aims at developing an analytical model for the velocity and turbulence in the wake of a wind turbine that takes meandering into account and where the expansion and the meandering of the wake can be independently calibrated. The velocity and turbulence breakdown presented in the companion paper allows a better interpretation of the ...

A simple vortex model applied to an idealized rotor in sheared inflow [PDF]
Wind Energy Science, 2023 A simple analytical vortex model is presented and used to study an idealized wind turbine rotor in uniform and sheared inflow, respectively. Our model predicts that 1D momentum theory should be applied locally when modelling a non-uniformly loaded rotor ...
