Ffowcs Williams-Hawkings Acoustic Analogy Model

Describe the Ffowcs Williams-Hawkings acoustic analogy model.

Features of Ffowcs Williams-Hawkings acoustic analogy model (FWH method)

• Sound pressure variation in the frequency characteristic (Sound pressure Level: SPL) visualization
• Placing the receiver on the far field has a low computational cost compared to the solution (which can reduce the analysis area)
• When running the sound pressure attenuation from the sound source with respect to the distance of the receiver, the reflection of the sound waves is not taken into account.
• The FW-H model is a typical model of the acoustic analogy
