I would like to calculate the sound induced by pipe flow. One of the ANSYS user recommeneded to couple Fluent and Mechanical as this link explains:How to setup acoustic simulations in Mechanical ? - Ansys Knowledge. However I'm not sure the details.
1) Do I have to caluclate the acoustic source information in Flunet using the Ffowcs Willinams and Hawkings model or the wave equation model?
2) What model do I use to calculate acoustic propagation in mechanical?
3) Are there any paper, help page or video showing the process?

in the material that I shared on that post, you can find a mention to Deterministic Aero Vibro-Acoustics simulation (DAVA). This requires a scale resolving transient fluid solution to be passed for acoustics propagation in Mechanical. For Mechanical setup, please address your question to the corresponding channel.
You can find an overview of the setup here: Aero Vibro Acoustics Demo - YouTube

Thank you so much for sharing the youtube channel. Still I couldn’t get how to generate acoustic source data in Fluent. Can we use either the FH-W model or the wave equation model?
