Single-Course English 5 ECTS


Overall Course Objectives

The goal is to provide the students with an understanding of how a wind turbine generates aerodynamic noise, how it can be mitigated and how it is transported in the atmosphere. This goal is supported by learning the numerical and mathematical modelling concepts. Furthermore, the students will learn how sound can be measured and physically interpreted.

Learning Objectives

  • explain the relevance of wind turbine noise for society
  • interpret and model basic acoustic wave motion
  • interpret and model the effect of flow on the acoustic wave motion
  • outline the mechanisms of flow turbulence and aerodynamic noise generation
  • apply the concepts above to identify and model aerodynamic noise sources of a wind turbine
  • apply techniques to reduce and control noise sources of a wind turbine
  • apply your knowledge of acoustic wave motion to atmospheric sound propagation
  • solve an aeroacoustic problem numerically
  • measure characteristics of a sound wave
  • process data from microphone array measurements
  • conduct and process data of an aeroacoustic wind tunnel experiment

Course Content

Aero-acoustics concepts, Linear wave equation and acoustic analogy, Noise mechamisms of wind turbines, Noise prediction models, Low noise wind turbine design, aeroacoustic measurements, sound propagation, Parabolic wave equations, Computational aero-acoustics, Conduction of a pre-defined wind tunnel experiment in the Poul La Cour wind tunnel and analysis of the data
