Course Description · Aerodynamics and Aeroelasticity

Keywords: BEM, aerodynamics, profile design, aeroelastic modeling.

Course Responsible: Martin O.L. Hansen



General Course objectives

The focus of the course is to learn about the aerodynamic and aeroelastic model components inside a full commercial aeroelastic code for load estimations on a wind turbine by coupling a structural model with a limited number of degrees of freedom with an unsteady aerodynamic model based on the Blade Element Momentum method.

Learning Objectives

A student who has met the objectives of the course will be able to:

  • Describe and apply an unsteady Blade Element Momentum method to model the aerodynamic forces on a rotor
     
  • Describe and implement 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 loads
     
  • 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

 

Content

In this course, you will derive and implement a simple aeroelastic model of a wind turbine in a numerical framework (e.g. Matlab or Python) that couples a structural model with a limited number of degrees of freedom with an unsteady aerodynamic rotor model. After you are done with the first part, you will couple this aeroelastic model to a basic controller and simulate the response of a wind turbine during normal operation.
