Actran AeroAcoustics

Predict the Noise Generated by Complex Flows

Actran AeroAcoustics is a module featuring advanced capabilities to predict accurately and efficiently the noise generated by turbulent flows. Results from an unsteady flow simulation performed with CFD codes such as SC/TetraTM (but also FluentTM, Star-CDTM, StarCCM+TM, PowerflowTM, OpenFOAMTM and others) are used by Actran AeroAcoustics to compute aerodynamic noise sources. The acoustic propagation from these aerodynamic sources is then computed to provide users with acoustic results such as noise levels and directivity.

Using Actran AeroAcoustics, the noise generated by any turbulent flow can be thoroughly predicted. Users can benefit from all features of the Actran software suite to study the interactions between the aeroacoustic noise sources and a vibrating structure, absorbant materials or acoustic traps such as resonators.

Through the use of a CFD code such as SC/TetraTM and Actran AeroAcoustics both fluid dynamics and acoustic performances of systems such as rotating fans, air conditioning modules or side mirrors can be improved thanks to a complete understanding of the physical phenomena involved in the noise creation process.

Actran AeroAcoustics offers high performance solvers and parallel processing features and is fully integrated in Actran pre- and post-processing environment: Actran VI. It can also be combined with Actran VibroAcoustics in order to address aero-vibro-acoustic challenges such as side mirror noise.

Sample applications:
  • Air conditioning modules (HVAC).
  • Side mirror noise.
  • Airframe noise (landing gear, trailing edge).
  • Air distribution systems.
  • Fan Noise.
