The general course objective is to learn and implement the basic models used inside a full commercial aeroelastic code for load estimations on a wind turbine. This includes a coupling between unsteady rotor aerodynamics and a dynamic structural model of the wind turbine. En studerende, der fuldt ud har opfyldt kursets mål, vil kunne:

• Run, alter and describe an unsteady Blade Element Momentum method to model the aerodynamic forces on a rotor
• Describe a dynamic wake/inflow model in the unsteady aerodynamic model
• Describe and implement unsteady 2-D aerodynamics in the unsteady aerodynamic model
• Describe and derive how the atmospheric turbulent inflow excites the rotor structure and leads to the turbine load
• Describe alternative aerodynamic models for rotors
• Couple the unsteady aerodynamic model with a simple structural model
• Implement a basic wind turbine controller
• Simulate and describe the static and dynamic response and loads on a turbine

In this course you will run, alter and describe a simple aeroelastic model of a wind turbine in a numerical framework (e.g. Matlab or Python) that couples a structural model with an unsteady aerodynamic rotor model. You will also play with and operate a basic controller and simulate the response of a wind turbine. The validation of the implemented models will be presented in small reports based on three assignments. Further, a video is to made at the end of the course based on all assignments. 20. august, 2018
