Aerodynamic Noise Simulation

FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization

Sound caused by pressure oscillation of fluid, such as wind noise, and sound caused by resonance can be predicted using Large Eddy Simulation (LES) and a weak compressible flow model. A Fast Fourier Transform calculation can be used within the CFD software to predict the frequency of noise. Predicting the noise generated by complex flows from steady CFD solutions allows us to study the noise generated by turbulent flows from CFD solutions.

Combining CFD and acoustic simulation software for study aerodynamic noise sources from flow simulations performed with CFD codes such as MSC Cradle, Fluent, StarCCM+ or OpenFOAM enable us to use the results from flow simulation obtained from CFD analysis, for export to the acoustic simulation software to synthesize the noise sources.
These sources are then imported into an acoustic computation and are then propagated. This procedure allows addressing the noise generated from turbulent flows in a much faster way than classic aero-acoustic approaches and it is specifically useful when relative levels between different designs are needed such as in optimization loops.
applications:
  • Air conditioning modules (HVAC).
  • Side mirror noise.
  • Airframe noise (landing gear, trailing edge).
  • Air distribution systems.
