Recommended prerequisites

Fundamental programming skills in Matlab, Python, or similar. 

Learning objectives - Knowledge

-state the early story about the Danish wind turbine industry,
-name different turbine concepts of extracting wind energy, list the main components of the horizontal-axis wind turbine, and describe its functionality from wind field to power grid,
-explain the 1-dimensional momentum balance between the induced velocity and the ideal aerodynamic power from a horizontal axis wind turbine and show how it leads to the Betz limit, 
-describe the structural blade constraints imposes on the aerodynamic rotor design,
-give an overview of the load cases to be considered in wind turbine design,

Learning objectives - Skills

-draw the velocity triangle for the local flow over a wind turbine blade section, and describe its flow components and how they can be computed,
-apply the blade element momentum (BEM) theory for designing an optimal wind turbine rotor for a single point of operation using a single airfoil for the entire blade,
-calculate the stresses in the blade under the static aerodynamic loading, and estimate the effect of wind turbulence on the extreme values of these stresses,
-validate a rotor design in terms of aerodynamic load, power, and elastic blade deformation using an existing computer code of wind turbine aeroelasticity,
-produce the designed rotor out of foam and test it in terms of power output and structural integrity,

Learning objectives - Competences

-evaluate one rotor design relative to another rotor design and develop theories about the causes for any differences in performances that are predicted in computations or observed in tests.

Content

In this summer course, we will follow the footsteps of the Danish wind turbine pioneer Poul la Cour who in the 1890’ties conducted the research and training within wind turbine technology, which eventually led to the success of the Danish wind turbine industry. We will learn about the momentum balance that exist between the wind velocities and the aerodynamic forces in the rotor plane of the turbine, and that leads us to the theoretical maximum power limit of 16/27 of the kinetic energy in the wind, the Betz’ limit. We will use this knowledge to design an aerodynamically optimal wind turbine blade under constraint that it is structural strong enough to withstand the aerodynamic forces. So, we must also learn to evaluate the structural integrity of a beam subject to distributed forces and use the result to redesign the blade if necessary. At the end of course, we are going to demonstrate the power output and structural integrity of our blades on a turbine rotor in real wind conditions. Besides this main track of the course, we will discuss other aspects of wind turbine technology e.g. the turbine controller, the drivetrain, and its electrical connection to the power grid.

Teaching Method

The teaching will consist of a combination of lectures and exercises. The exercises are both theoretical and practical. Part of the lectures will be focused on the theory needed for the exercises, while others will give a more general overview of the mechanical and mechatronic topics related to wind turbine technology.

Description

The examination is based on an overall assessment of:
  • Attendance (80 %)
  • Oral exam as described above
Oral exam consisting of a demonstration of the rotor designed by each group followed by an individual oral exam in the learning objectives of the course. The final grade is based on an overall assessment of level of participation, performance in the group work, and individual fulfilment of the learning objectives.

Additional information

Enrolment is limited to 10 students. If more applicants than places, applicants who meet the mandatory requirements are prioritised according to the below selection criteria: 

  1. Undergraduate and graduate students from partner universities (exchange); international undergraduate and graduate guest students (fee-paying); undergraduate and graduate students from other Danish universities.  
  2. Ph.D students from partner universities and other international Ph.D. students; other applicants.  
Students are prioritized on a first come, first served basis, i.e. according to the time we receive your complete application.  

In case a course is filled up, we try to offer you an alternative course from your list of priorities. All final decisions about admission will be sent out continually.
