Aeroacoustics with AIAA

OpenCFD is proud to present OpenFOAM training as part of the AIAA course offering.

The training takes place on 7 June 2022. The training is fully online and in US time zone. Register here.

This course covers Theoretical and Applied concepts in Computational Aeroacoustics (CAA) using OpenFOAM, touching on progressive Multiphysics design challenges, e.g. Aero-Vibro-acoustics (AVA). The course organisers are leading experts in flow-noise source prediction, propagation and noise abatement in all engineering sectors including transportation (Automotive, Aerospace, Marine, Rail), energy, power generation, building environment and turbomachinery.

The training provides examples of process and best practice, which are useful to existing OpenFOAM users wishing to broaden their application knowledge of OpenFOAM towards Aeroacoustics, Hydroacoustics and Aero-Vibroacoustics. All features demonstrated in this course are part of the Official release of OpenFOAM.

Topics Covered

  • Surface based (shear-flow correlation) * Volume based (Lilley-Proudman correlation)
  • Transient:
  • Appropriate physics modelling and boundary conditions for aeroacoustics
  • Numerical control settings in OpenFOAM
  • Pure acoustics in OpenFOAM?
  • Spectral postprocessing using the built-in OpenFOAM point-based and surface-based temporal-Fourier analysis tools
