1. Internship | Standstill Vibrations: Full-scale field tests and numerical Simulations

Locatie: Rijswijk

Opleidingsniveau: Master

Uren per week: Fulltime - 40

Internship | Standstill Vibrations: Full-scale field tests and numerical Simulations

About this position

Wind energy industry is struggling with the topic off standstill vibrations. To date, the simplified methods applied in rotor blade design are not adequate to capture the underlying physics. As a result, findings regarding Standstill and/or Vortex Induced Vibrations (SViV) only become apparent late in the design or production process and may require revision of the rotor blade design. This master thesis assignment contributes to tackling this issue by performing field measurements and corresponding numerical simulations.

What will be your role?

You will perform an exploratory study of the critical conditions for SVIV to occur both in the simulation domain, as well as experiments in the field and compare these. Furthermore you will explore innovative models like a double wake model to assess the effects of using unsteady airfoil polars in predicting SVIV. Optionally you will use a wind tunnel database as an intermediate step to explore the possibilities of innovative unsteady airfoil models.

You will work within a team of highly motivated professionals that are happy to supervise you along the way.

What we expect from you

Your communication skills allow you to convey a difficult technical topic in an understandable way. Furthermore you have:

• Sound knowledge of aero-elasticity, aerodynamics and wind turbine modelling.
• Proven programming experience, for instance in coding your own rotor aerodynamics code.
• Good critical thinking skills and ability to think outside the box for scientific research. Aptitude to use scripting software like Matlab and Python.

What you'll get in return

You want an internship opportunity on the precursor of your career; an internship gives you an opportunity to take a good look at your prospective future employer. TNO goes a step further.

• A highly professional, innovative internship environment, within a team of top experts.
• A suitable internship allowance (615 euro for wo-, hbo- and mbo-students, for a full-time internship).
• Possibility of eight hours of free leave per internship month (for a full-time internship).
• A free membership of Jong TNO , where you can meet other TNO professionals and join several activities , such as sports activities, (work-related) courses or the yearly ski-trip.
• Use of a laptop.
• An allowance for travel expenses in case you don't receive an OV-card.
