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

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 ...
