Wake Deflection in Long Distance From a Yawed Wind Turbine
Journal of Energy Resources Technology, 2017 Since it is important to prevent the wake produced by upstream wind turbines from interfering with downstream wind turbines, a method of deflecting such wakes is desired. In this paper, we present the coupled analysis results of a computational fluid dynamics (CFD) simulation involving a three-bladed rigid wind turbine with a yaw control system that ...

Application of engineering models to predict wake deflection due to a tilted wind turbine [PDF]
, 2012 It is a known fact that the power produced by wind turbines operating inside an array decreases due to the wake effects of the upstream turbines. It has been proposed previously to use the yaw mechanism as a potential means to steer the upstream wake away from downstream turbines, however such a mechanism introduces control complications due to ...

Deflection of wind turbine wakes by yaw misalignment – Simulation and field testing [PDF]
, 2020 The primary objectives of wind farm control is to mitigate the negative effects of the aerodynamic interactions between turbines, which can lead to reduced power yields and to increased structural loadings. In the scope of this thesis, field experiments and numerical simulations were performed to better understand the potential of wake deflection ...

The characteristics of helically deflected wind turbine wakes
Journal of Fluid Mechanics, 2023 The helix approach is a new individual pitch control method to mitigate wake effects of wind turbines. Its name is derived from the helical shape of the wake caused by a rotating radial force exerted by the turbine. While its potential to increase power production has been shown in previous studies, the physics of the helical wake are not well ...
