E​RCOFTAC Course

 

Computational Aeroacoustics, IV

26th - 27th March 2024

TU Wien, Building BA, Getreidemarkt 9, 1060 Wien, Austria

 

Organizers:
This course is intended for researchers in industry and in academia including Ph.D. Students with a good knowledge in fluid mechanics, who would like to build up or widen their knowledge in the field of aeroacoustics (modelling, computational tools and industrial applications).

 

It will provide a comprehensive overview of aeroacoustics theories:
  • Lighthill analogy and vortex sound theory,
  • FWH analogy,
  • hybrid approaches,
  • wave extrapolation methods,
  • duct acoustics
and of the issues of the direct computation of aerodynamic noise using CFD methods:
  • Large Eddy Simulation,
  • Lattice-Boltzmann Method.
A number of practical problems involving the coupling between CFD and CAA will be also thoroughly discussed (e.g. how design a mesh size for aeroacoustics applications, inclusion of mean flow effects via hybrid formulations such as the acoustic perturbation equations, presence of surfaces, aero-acoustic couplings) and realistic applications performed by the instructors (aeronautics, car industry, propulsion, energy) will be discussed. Advanced computational aeroacoustics methods, as well as what we can learn from the direct computation of aerodynamic noise, will also be presented. Finally, specific topics reflecting participant interests will be discussed.
