What will you be doing?

Equipping wind turbine blades with winglets can improve the power production of rotors within limited load increase. What model fidelity is required to achieve an aerodynamically sound design of winglets for wind turbine blades? In this project you will be seeking to answer this question by comparing the results of simulations performed with codes having different fidelity. The core part of the assignment will be the development of a Computational Fluid Dynamics (CFD) model of a wind turbine rotor equipped with winglets, the result of which will be used as a reference for the code comparison.
The project consists of the following tasks:
  • A literature survey on wind turbine winglets, focusing on methods used in their analysis and design.
  • Development of a CFD model of a wind turbine rotor equipped with winglets.
  • Together with TNO researchers, evaluate the results from the calculations and understand differences with results from other models.
  • Report and present findings.

What do we require of you?

We are looking for MSc students in technology with the following characteristics:
  • Good knowledge of fluid mechanics and an interest in numerical methods.
  • Competent in CFD modelling packages.
  • Knowledge of a programming language (eg, Matlab).
  • Independent working attitude.
If you are the one that we are looking for, please submit your CV and motivation letter in English.

What can you expect of your work situation?

Your work will be carried out in our Wind Energy department. Due to the Corona situation you will most likely work from home, remotely supervised by one or two Wind Energy experts. When the Corona situation improves you may work from Petten and/or Delft. The Wind Energy department houses approximately 60 enthusiastic, academic professionals who have in-depth knowledge of wind energy technology.
Your activities are connected to a national industrial project from the TKI Wind op Zee R&D, focusing on the design of innovative tips to enhance performance of wind turbine blade.

What can TNO offer you?

You want to work on the precursor of your career; a work placement gives you an opportunity to take a good look at your prospective future employer. TNO goes a step further. It’s not just looking that interests us; you and your knowledge are essential to our innovation. That’s why we attach a great deal of value to your personal and professional development. You will, of course, be properly supervised during your work placement and be given the scope for you to get the best out of yourself. Naturally, we provide suitable work placement compensation.
