Thanks for the response, Rob. I spent some time looking into the code and the physics, so I think the approach I'll take is this:

  1. Calculate pressure-velocity waves in ANSYS Mechanical.
  2. Use those fields to calculate a force-field in the domain.
  3. Export to Fluent and hold in memory as User-defined memory
  4. Write a UDF in Fluent to use that force field in addition to drag and gravity forces.

The Fluent Acoustics seem like they may be a bit overkill for what I need and what I've seen other analysts do in literature. 

My next problem is using ANSYS Mechanical for the acoustics simulation and exporting the results to load into Fluent. Would you have any tips on doing that? Could I simply import the results file from a Harmonic Response analysis into Fluent and have access to the result fields from ANSYS Mechanical? I assume I'll actually need to export as some other format and write a UDF to read those results into memory...
