Siemens Digital Industries Software Aero-acoustics
Simcenter offers an extensive library of accurate models for predicting aeroacoustics noise sources, including steady-state models, direct models (DES/LES), propagation models, and acoustic perturbation equations (APE) solver.
Flow induced aeroacoustic noise is a significant component of the acoustic signature of a vehicle or other products. Predicting and understanding noise generation mechanisms, localizing sound sources, identifying transmission paths and predicting system acoustic response is key to good acoustic design. With Simcenter, you can reduce noise, improve sound quality and gain a competitive advantage while reducing expensive physical testing and reducing flow-induced vibrations/fatigue. Either the noise-inducing turbulent flows as well as the sound wave propagation can be resolved directly, or the flow simulation can be combined with so-called hybrid methods for sound propagation.

Either the noise-inducing turbulent flows as well as the sound wave propagation can be resolved directly, or the flow simulation can be combined with so-called hybrid methods for sound propagation.
Reduce noise pollution and extensive physical testing by solving both noise sources and sound propagation simultaneously in a single model. Accurately model aeroacoustic noise sources with Detached Eddy Simulation (DES) and Large Eddy Simulation (LES) approaches. Predict convective turbulence and methods for propagating noise in near field. Simulate two-way, coupled flow-noise interaction like whistling, buffeting and sound wave-induced vortex shedding, muffler and HVAC noise.
Utilize a hybrid method where CFD simulation captures sound sources, and additional simulation steps propagate sources to an observer location. Utilize either integral Ffowcs Williams & Hawkings methods, or acoustic wave computation model. Applications include estimating fan noise, propeller noise, jet noise, and side mirror aeroacoustic noise.
Quickly identify sources of aeroacoustic noise in Reynolds-Averaged Navier Stokes (RANS) simulations and estimate mesh cutoff frequencies.
