Rigid Actuation Of The Wind Turbine
Authors / Details: George Barakos, University Glasgow; Vladimir Leble, University of GlasgowAbstract
The possibility of a wind turbine entering vortex ring state during pitching oscillations is explored in this paper. The work first validated the employed CFD method, and continued with computations at fixed yaw of the NREL Phase VI wind turbine. The aerodynamic performance of the rotor was computed using the Helicopter Multi-Block flow solver. This code solves the Navier-Stokes equations in integral form using the arbitrary Lagrangian-Eulerian formulation for time-dependent domains with moving boundaries. With confidence on the established method, yawing and pitching oscillations were performed suggesting partial vortex ring state during pitching motion. The results also show the strong effect of the frequency and amplitude of oscillations on the wind turbine performance.
