Abstract

Wind turbines face harsh inflow conditions when operating in the atmospheric boundary layer or in the wake of other wind turbines. The incoming velocity field can change within seconds due to the turbulent structures it contains, resulting in a rapid change of several degrees in the angle of attack for the rotating blade. Aerodynamics are hence rapidly altered, leading to changes of the occurring forces on the rotor. Such dynamic forces cause the blades to twist and bend, accelerating fatigue and reducing the lifetime of a turbine Spinato et al. (2009).

Author Biography

Tom T. B. Wester, University of Oldenburg, ForWind - Institute of Physics, Germany

Studied physics in Oldenburg, focused on boundary layer flows of airfoils in my masters.  I continued to work on turbulent and tailored inflow generation in wind tunnels using active grids.  In the process I also investigated the evolving flow around airfoils by means of stereo PIV and ended up investigation the flow around rotating model wind turbines under customized flows.
