Is there any public database with CFD output data?
 

I'd like to gather multiple types of good CFD simulation data (good = somehow validated), created mainly with SPH or Lattice-Boltzmann methods. Is there any public database with such stuff that an ordinary researcher can access? Or would be better to ask specific people/companies/R&D labs for such data (if possible to be shared)?

The reason for this that I'd like to train some ML models based on these simulation outputs and prototype a small idea I have.
