Hi,
I 'm a new user of SU2. I have saw the paper about SU2 in AIAA. I saw there is a wave equation (FW-H) in SU2. I want to use SU2 to do the aerodynamic noise simulation. But there is no tutorial about noise analysis. Would you please give me a tutorial about aerodynamic noise ?

thanks

Hi zhereal,

Thanks for your interest in SU2, and I'm glad that you saw the paper! The aeroacoustic components in SU2 are currently in the research stage (we don't have a tutorial available at the moment), but if you are interested in more detail, please see the following paper: http://adl.stanford.edu/papers/AIAA-2012-5598.pdf.

Also, feel free to investigate the wave equation solver that can be found in solution_direct_wave.cpp.

All the best,
Tom

Thank you economon for the reply. Next, I will see solution_direct_wave.cpp and the paper you recommended. Thx


Cheers,
Zhereal.

Has there been any progress in this since 2012?

I'm interested in far-field noise computations, specifically for propellers. If I saved surface pressures on the blades at every n time-steps during a rigid body, unsteady, navier stokes simulation, how would I use these to propagate pressures to a desired location and get a noise spectrum using the overlapping grid method?

The paper mentions loading and thickness noise. Is there a broadband noise implementation too?

To be more direct, I'm interested in something similar to what WOPWOP does, while making use of the adjoint optimization capability of SU2.

Thanks.

p.s. I also want a purple unicorn. It's that time of the year again.

Hello Nomad,

Have you had any progress in terms of how to apply the wave equation solver in SU2 for the solution of the FWH equations? I am also interested in finding the noise or the acoustic pressure at a surface enclosing a jet stream coming out of a nozzle. I would really appreciate if you could please guide me if you can.

Thank you!!

Hi, Have you found how to apply this FWH in SU2 solver? I am doing the same nozzle stuff, so just wondering if you were able to find the way to get it? Thank you in advance for help
