iconCFD Acoustic is a tool for Computational Aero-Acoustics, which deals with simulating the noise produced by air flow in or around objects. CAA tasks include far field noise prediction, aero-acoustic source identification and acoustic data analysis in the frequency domain.
-
Lighthill – Curle (L-C) sound propagation model
Far field noise prediction based on aero-acoustic source terms on solid walls and in the fluid volume
-
Ffowcs Williams – Hawkings (FW-H) sound propagation model
Far field noise prediction based on aero-acoustic source terms on a closed control surfaces around an area of interest
-
Acoustic source identification
Acoustic source term fields and acoustic power fields can be calculated on surfaces and in the volume
-
FFT post-processing
Pressure fluctuation data from probes in the simulation volume or far field propagation can be transformed into the frequency domain and output as Sound Pressure Level spectra
