Unsteady aerodynamics of a novel two-bladed wind turbine and a three-bladed wind turbine equipped with an innovative load reduction concept are investigated in the present paper using Computational Fluid Dynamics (CFD). The load reduction concept consists of coupled leading and trailing edge flaps. Unsteady aerodynamic effects caused by flap deflection are shown and a suitable temporal discretization for efficient simulation of coupled leading and trailing edge flaps is found. The behavior of the two-bladed turbine regarding the aerodynamic loads under extremely yawed conditions is presented and associated to the local flow conditions. The results of the studies allow a better prediction and understanding of unsteady aerodynamics of wind turbines.
