Learning outcomes

After successful completion of the course, students are able to understand the physical mechanism of flow induced sound and have mathematical models at hand for analytical estimations as well as for numerical simulation.

Subject of course

There are many application of flow induced sound in daily life: aircraft noise (jet engine), traffic noise (flow around cars, exhaust noise), musical instruments (wind instrument, organ pipe), etc. The course will concentrate on the following topics:

  • Basic equations of flow dynamics and acoustics
  • Aeroacoustic analogies: Lighthill-, Curle- sowie Ffowcs Williams & Hawkings Analogie, acoustic perturbation equations
  • Sound propagation computation applying Green¿s functions
  • Applications: edge tone, car side mirror, airfoil, rotor blades, human phonation

 

Teaching methods

The course will be interactive and the knowledge will be communicated by multimedia-based presentation using practical examples. Thereby, a high priority is placed on the physical understanding.

Mode of examination

Written and oral
