Chris_321 is on a distinguished road

i'm looking for a CFD Software to predict aeroacoustic noise in HVAC systems. I'm wondering whats the best Software choice. There are many publications with EXA Powerflow and Starccm+.

EXA is using a LBM Method while Star is using NS equations.

I think star could be the better choice because it can solve rans equations and use BNS models in the early development stage to have fast results. Do you have any experience with one of the solvers for internal aeroacoustics?
