OpenFOAM® transient and compressible solvers directly capture turbulence pressure fluctuations (broadband), coherent shedding (tonal) and pressure-wave propagation in the fluid medium.

Noise transmission methods through simple structures, analysis via acoustics analogies and Adjoint Optimisation objective function are included in the solver-suite, complimented by validated processes for aero-vibro-acoustics (AVA) Fourier-based Wavenumber-Frequency decomposition analysis [1] and coupling with full-physics vibroacoustics solvers [2, 3].

Appling OpenFOAM to

  • Internal cabin noise transmission from external wind noise
  • Side-window and sunroof buffeting including interior cabin damping
  • HVAC duct noise
  • Underhood and HVAC fan cooling
  • Frequency range up to the normal human peak range (~5kHz)
  • Electric Vehicles in production
