Abstract

- The aerodynamics of a wind turbine is governed by the flowaround the rotor, where the prediction of air loads on rotorblades in different operational conditions and its relation to rotor structural dynamics is crucial for design purposes. One of the most important challenges in wind turbine aerodynamics is therefore to accurately predict the forces on the blade, where the blade and wake are modeled by different approaches such as the Blade Element Momentum (BEM) theory, the vortex method and Computational Fluid Dynamics (CFD).A free vortex wake method, based on the potential, inviscidand irrotational flow, is developed to study the aerodynamicloads. The results are compared with the BEM method,the GENUVP code and CFD.
