Hours a weekFulltime – 40
One of the opportunities to further improve the design of modern wind turbine blades is to focus on the development of specific innovations for the blade tips. In this framework, designing wind turbine tips based on winglet-like shapes is a promising application. If properly designed indeed, such shapes can improve the aerodynamic efficiency of the rotor by reducing the tip losses. However, the aeroelastic performance of blades with winglets needs to be carefully verified to evaluate the effect that similar devices have on the structural loads. The standard aeroelastic blade design tools used by the industry are based on the blade element momentum (BEM) theory. BEM theory is a reliable and fast approach, but it is based on several simplifications which make it unsuitable to account for the complex aerodynamics of winglets. More advanced aerodynamic approaches, like Free Vortex Wake (FVW) methods, allow the modelling of those aerodynamic phenomena occurring around a winglet. Despite being more computationally expensive than BEM, FVW-based tools have become fast enough to be integrated in aeroelastic calculations.
What will be your role?
- Performing aeroelastic simulations of a real wind turbine rotor mounting these blades with winglets.
- Post-processing and critically analyzing the results based on the existing literature.
- Preparing an internship report describing the work performed and the results obtained.
The internship will be carried out in close collaboration with at least two TNO researchers and will offer the candidate the opportunity to be part of an international research group working on Wind Energy. The selected intern will also interact with engineers from a partner company.
