Abstract
A numerical analysis of the DTU 10-MW RWT wind turbine aerodynamics is presented in this work. The development of an innovative methodology based on three-dimensional computational fluid dynamics allowed to tackle two challenging problems related to this application. On one hand, the impact of blade deflections on rotor performance was assessed in a rotor-only context. Different blade configurations were studied, including the installation of Gurney flaps and the consideration of prebending and preconing. On the other hand, flow unsteadiness of the full machine (i.e. including the tower) was modeled by means of the Non-Linear Harmonic method. This approach allowed to characterize local aspects of the flow and the impact of rotor-tower interactions on the computed loads.
