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. In this work, a two-dimensional analytical model is proposed for far wake modeling under yawed conditions by taking the ...

Validation of wind turbine wake models with focus on the dynamic wake meandering model [PDF]
Journal of Physics: Conference Series, 2018 This analysis compares current wake models, such as the Sten Frandsen turbulence model, an engineering wind speed deficit and turbulence model developed by G. Chr. Larsen, the N. O. Jensen wind speed deficit description and three variations of the dynamic wake meandering (DWM) model to measurements from onshore wind farms. Special attention is given to
