Prediction of dynamic loads and induced vibration in stall

In the Fluid Mechanics Section a group of 4 researchers have worked with wind energy research during 20 years. The primary fundings have been both through EU projects and projects sponsored by the Danish Energy Agency. A major part of the projects concerns the predictions of the wind turbine loadings during operation; here the atmospheric turbulence combined with the gravity is significant and is the cause of most of the structural fatigue life consumption. This time-dependent loading excites the structure to vibrate, which again influences the local angle of attack. It is important to know the stresses caused by this loading in order to estimate the fatigue damage of the structure. This research is called aeroelasticity.
