Large Eddy Simulation of Yawed Wind Turbine Wake Deformation

Wind turbine wake redirection drawn by a yaw control has been proposed as strategy to improve the performance of wind farms. However, characteristics and development curled structure deformed action rotor are not well understood. In present study, behind imparted with various angles subjected uniform inflow was investigated using large-eddy simulation. The NREL 5MW reference modeled an actuator disk rotation study deformation process wake. source vertical asymmetry in found be based on interaction global counter-rotating vortex pair induced angle. angle had profound influence distortion its trajectory, whose effect naturally mitigated downstream distance.
