Hi everyone,

I am currently working on an aeroacoustic problem. Essentially I have at the inlet about 50 m/s velocity airflow in the system, which is accelerate in the nozzle (choke) and reach 1 Mach , and because of that noise created (shear stress).

I have to analysis the noise level after, near at the outlet in the field (not on surface).

The flow is steady state so I can use only Broadband Noise method.
Using turbulent model : SST

My question is:
What I would like to know is it possible to use measuring points (like microphone) in the field using broadband noise method in steady state flow?
If yes, can someone tell me how to do that?

I am desperate.

Thank you for your answers.

Richard
