Course content

The course will perform calculations of the energy potential in wind. Methods of measuring wind velocity will be taught, for the calculation of area or site energy potential. Different technologies for wind- power plants will be shown. The course consists of a large project concerning a specific technology within the field of wind-energy. The project will be carried out in groups.

Learning outcome

The course provides the student with knowledge about:
- Energy potential in the wind.
- The flow characteristics and turbulence in the wind.
- Windturbines basic design and introduction to the main components.
- Windturbines; power- and thrust coefficients according to Betz theorem.
- Actuator and Rotary Disc theory.
- Design of a turbin blade by using The Blade Element Momentum method.
The course gives the student insight about:
- Renewable energy potential in the world.
- Aerodynamics of an airfoil.
- Design loads for windturbine.
Skills:
The course should enable the student to:
- Calculate the main dimension of windturbines.
- Calculate the energy produced from wind farm.
General competence:
The course should give the student.
- When the student has finished the course, he/she shall have knowledge about Wind turbines.
- The student will be able to use this knowledge in projects where these machines are a part of a power plant.

Learning methods and activities

Lectures. Excercises, both with emphasis on experimental laboratory work, and theoretical problems. Mandatory excercises and project report will constitute 50% of the final grade. The lectures and exercises are in English when students who do not speak Norwegian take the course.

Further on evaluation

Portofolio assessment is the basis for the grade in the course. The portofolio includes a final oral exam (50%) and mandatory exercises and project (50%). The result for the parts are given in %-scores, while the entire portofolio is assigned a letter grade.
For re-take of an examination, all assemssments during the course must be re-taken.

Recommended previous knowledge

Basic fluid mechanics.
