Hi everyone ,
I am implementing Acoustic model in FLUENT. Geometry is 2D. By using FW-H model, I am facing difficultly to understand these things. ( I have already read FLUENT manuals and one tutorial )
1) It is very important and necessary to define accurately Source Correlation Length in 2D geometry. I do not know this parameter. how to calculate it. my geometry is very simple, just a rectangular to 10*20 mm.
2) What should be the source zone and type ? In 2d-cylindrical tutorial, I read it is a cylindrical wall. My geometry have 0.5 mm inlet a bottom. Is it the source zone and type will be Velocity INLET ?
3) Where will be the receivers position ? I have to monitor the the time history when gas passes through from INLET ? I read one paper there was one monitoring point which is away form the inlet.. I could not understand.
4) What is FW-H integral surface ? I think, the under investigation portion has very fine mesh. this is called FW-H integral surface. But I am not sure about it..
Any type of advise, guideline or tutorial will be highly appreciated. Thanks in advance..
Hey,
just a small note from my side: two years ago I implemented an acoustic model for incompressible fluids. If I remember it correct, it was done based on the definition of bulk modulus combined with a prescribed speed of sound. Everything was done via user-coding.
Thanks for sharing your experience.. "Everything was done via user-coding." Does it mean that you wrote your own user define functions in acoustic model ?

Is it possible to do two-phase simulation for 3D pipe leakage using FW-H Acoustics model?
Yes, It is possible to simulate two phase, 3D case in FW-H model. But I do not have experience about pipe leakage problem. Mutiu A. Adegboye
