What will you be doing?
The current trend in wind energy is to scale up the wind turbine rotor size to harvest more energy for a given area of turbine location. On the other hand, it is also possible to improve the aerodynamic performance of the existing wind turbine blades with some additions like blade add-ons, root spoilers, and winglets.
Introducing winglets to existing blade design will enhance the mean shear and turbulence in the outer part of the wake that will cause higher levels of turbulence in the far-wake region. So, introducing winglets will not only increase the power and thrust of the turbine under consideration but also will potentially have higher energy flux for the wind turbines downstream.
Although a detailed analysis of this flow problem would require experiments or full CFD simulations, employing a 3D inviscid flow panel method would reveal some key features and will allow reducing the selection of the necessary design parameters. Within this study various winglet configurations will be analyzed by the mentioned 3D inviscid flow panel method. An existing mesh generation tool will be used to create the surface mesh.
The 3D panel method is implemented in C++ where the mesh generation tool is implemented in Fortran. An essential part of the task is to be able to implement improvements into these codes if necessary.
The major steps of the study will consist of the following:
- Literature study
- Introduction to 3D Panel code
- Implementation in C++ (when necessary)
- Verifying/validating the current method
- Testing various winglet configurations
This MSc thesis project is planned for a period of 9 up to 12 months at TNO Petten.
What do we require of you?
Preferably you have a background in Aerodynamics. You have a basic knowledge of CFD schemes and/or numerical analysis methods. Additionally, basic knowledge of algorithm development and a high-level programming language (preferably C/C++) is necessary for this project.
What can you expect of your work situation?
TNO is an independent research organisation whose expertise and research make an important contribution to the competitiveness of companies and organisations, to the economy and to the quality of society as a whole. Innovation with purpose is what TNO stands for. With 3000 people we develop knowledge not for its own sake but for practical application. To create new products that make life more pleasant and valuable and help companies innovate. To find creative answers to the questions posed by society. We work for a variety of customers: governments, companies, service providers and non-governmental organisations. Working together on new knowledge, better products and clear recommendations for policy and processes. In everything we do, impact is the key. Our product and process innovations and recommendations are only worth something if our customers can use them to boost their competitiveness. Your work will be carried out in our Wind Energy department in Petten, with approximately 60 enthusiastic, academic or bachelor professionals who have in-depth knowledge of wind energy technology. Your work at TNO will be supervised by one or two of these Wind Energy experts. Where possible your activities are connected to our projects. These projects can have a research orientation but we also have projects with a strong industrial focus.
