Hello! I ran through a problem while performing acoustic Simulations, it would be better to get help from you who have more experience and information about the simulation I'm carrying out. Your ideas are welcome.

Here is the point. I tried to simulate the displacement pump (Gerotor) using FLUENT for acoustics.
Viscous Model : K-e
Acoustics Model : Ffows-Wiliams & Hawkings
(Simulation's Receiver Coordinates matched with Experience Environments.)
Sol Method : 1st order Upwind
It was revealed that the simulation results are higher than those obtained by experiment With a difference of 60 dB.

here's the question. is that possible to apply casing CAD in fluent? I mean when calculating this simulation. In my opinion, I have just used fluid section Mesh. without case of pump...

I hope that if you help me with some information or function to use, I can obtain more accurate simulation results.

Thank you for reading all about my post and hopefully we can get this problem solved soon.

have a nice day!
