Finite element based lifetime predictions of wind turbine blade coatings

Operating turbines suffering from leading edge erosion (LEE) experience significant (up to 5%) annual energy production (AEP) loss and require expensive maintenance campaigns. Evaluation of state-of-the-art coating systems relies on rain erosion testing (RET) with no accepted method for the computational evaluation of the coatings lifetime. In...

Automated truck platoon model development and effect study of the lane change location on different motorway road sections

Truck platooning is seen as a method to reduce truck emissions and labor hours in the transport industry. The effect that truck platooning will have on the other traffic receives less attention. In this thesis a methodology is proposed to model truck platoons, including a platoon level controller for lane changing. The model is used to estimate...

Overlaatconstructie te Onitsha, Nigeria

In de rivier de Niger in Nigeria zal ter hoogte van Onitsha een dam worden gebouwd. Deze dam met een lengte van ongeveer 3200 m moet een reservoir creeren door opstuwing van het water van de Niger. De door de gehele dam veroorzaakte waterstandsverhoging beoogt in de eerste plaats opwekking van energie middels een waterkrachtcentrale. Doordat het...
