Fluid Acoustics

Oliver Litfin, M. Sc.

Acoustic Spectrum

The research group „Fluid acoustics“ mainly deals with flow induced noise. Main topics are:

  • Investigation and characterization of acoustic sources
  • Investigation oft he effect of mean flow on sound propagation
  • Development of measures for reducing or damping flow induced noise

Most oft he work is concerned with air at low Mach numbers (Ma < 0.3). Main focus is on applications involving turbomachinery. Industrial application areas include aerospace, automotive, rail vehicles and small scale turbomachinery.

No projects found.

Among the currently or recently studied topics there are:

  • Study of academic test cases
  • Design of turbo machines
  • Aeroacoustics of aerofoils
  • Aeroacoustic modeling using numerical methods
  • Thermodynamic techniques for noise reduction
  • Noise reduction and stealth technology from the animal kingdom

The research group employs experimental as well as numerical methods.
