Aeroacoustics modelling

vauntedmango · February 29, 2024, 12:39

Hello!

I am trying to start a CFD case which involves two key requirements that I would assume will influence the modelling technique used. I want to simulate far field noise data for an airfoil that is equipped with mechanical blowing in certain parts of the airfoil. I have found several useful papers on simulating either one, but am struggling to find resources that include both and would appreciate some guidance on this. For more context, the flow is subsonic, with no BL tripping and simulation should be 3D or atleast quasi-3D

Thank you

Aeroacoustic modeling is a post-processing step after you simulate the flow. So you don't need a paper that does both. If you have papers that show you how to do Step 1 and then Step 2, just combine the knowledge you have gained and you can step Step 1 and Step 2. Hint, step 2 comes after step 1.
