Hello, all!

I'm currently working on acoustic simulations of a centrifugal fan inside a casing. Initially, my strategy was to obtain acoustic sources in Fluent (via FW-H model) and then import this data to Harmonic Acoustics, where I, presumably, could calculate the propagation of sound waves taking into account reflection and scattering on the casing walls. Unfortunaly, this is not possible, as I can only import pessures onto a structure, not to an acoustic domain.

Is there a way I could do this analisis (sound generation in centrifugal fan + propagation in duct accounting for reflection and scattering) entirely within Ansys without needing to run a transient, compressible flow simulation with large scale turbulent model ('cause that would take a very long time in my setup)?

Thanks!

Hello,
Did you mean Ansys Mechanical?

Hi RK
I want to do this all within Ansys. I know that sound sources can be obtained from Ansys Fluent via FW-H model, but this model only considers propagation in a free-field. I'm searching for a method to process this acoustic source data in some way to calculate the sound propagation with reflections and scattering.

Hi,

I am facing the same problem right now, did you find a solution?
