Internship | Wind Turbine Aerodynamics

As an intern (on MSc level) in the Wind Energy research group, you will work with topic experts to further explore the versatile field of wind energy research and help create a sustainable future using renewable energy sources. Vortex generators (VGs) are commonly used by wind turbine blade manufacturers to improve performance of turbine blades. VGs are typically used near the root section of wind turbine blades and help to keep the flow attached even at high angles of attack that are observed in this region. CFD modeling the effect of VGs is cumbersome because of the excessive mesh resolution requirements to resolve all the flow details. This places a severe limitation on the design of innovative VG concepts for wind turbine blades. In this assignment, you will be expected to implement and validate an analytical model for VGs in high fidelity CFD codes.

In this assignment you will implement the BAY method for modelling VGs in one of the higher fidelity CFD methods (e.g. SU2 or OpenFOAM) which are in use at TNO to model the overall airfoil performance with VGs. The research will start with a literature survey on the vortex generators (VGs) and modelling concepts for the higher and lower fidelity methods. To see the effects of the VGs, the 3D flow simulations will need to be performed for relevant Reynolds numbers both with the BAY model and body fitted mesh. Finally, the validity of the BAY model will be established based on comparison against experimental and numerical data. Your work will be carried out in our Wind Energy department. This department houses approximately 60 experts with an in-depth knowledge on wind energy technology. During the internship you can work from our offices in Petten and/or Delft, and will be supervised by 2 to 3 Wind Energy Experts.

We are looking for MSc students (or intern) in relevant areas i.e. (Wind)Energy Technology, Aerospace Technology, Mechanical Engineering etc with the following characteristics:

• Programming experience in C++/FORTRAN;
• Knowledge of Pointwise, Paraview, SU2 and OpenFOAM or willingness to learn these tools;
• Enthusiasm for research and technology development;
• Interest in wind energy;
• Technical knowledge of wind turbines and aerodynamics;
• Independent working attitude;
• Good knowledge of the English language;
• Available to work at least 32 hours for a period of 4 to 6 months.
