Fluid-acoustic structure interaction

Please login with a confirmed email address before reporting spam

Hello to everyone,
I would like to model the acoustic field at the outlet of a ducts system ( a muffler) with a fluid flow inside by using comsol.
More precisely I want to know the sound pressure level at a specific distance from the outlet of the muffler.

I am quite confused of the wide variety of physics available in comsol.

Can anyone suggest me how to model the coupling between structure of the muffler and the acoustic field generated by the flow?
