The effect of atmospheric boundary layer turbulence at a height of wind turbine installation

Abstract EN

The aim of this paper is to investigate the overlap between lower atmospheric boundary layer and real wind turbine wake which installed not far from ground surface, Here we adopted rotating actuator-disk model (RADM) as a complex model of 3D actuator-disk model, virtual blade modeling (VBM) and tip loss correction, in order to get more reliability and satisfied result.

Wind turbines have grown significantly in size over the last years and, it generally placed in an atmospheric boundary layer, then the assumption of uniform wind velocity cannot be valid.

The lower part of atmospheric boundary layer has a high level of turbulence intensity and great velocity gradients, then when wind turbine placed in these conditions, a high rate of fluctuation will occur subsequently power losses in wind farms, and change wake turbulence character which affects the flow-induced dynamic loads on downwind turbines
