How to simulate engine noise

Ryuzaki · May 29, 2023, 01:50

Hello dear CFD enthusiasts,

I have been trying to simulate all automobile noise using CFD. In addition to aerodynamically generated noise I need to obtain engine noise. Is there any way to simulate both engine and aerodynamic noise simultaneously?

Can I define the noise value given in the engine dataset as the source term?

Or, for example, let the engine noise be 110 dB and the aerodynamic noise of the vehicle 80 dB. How can I add these two values?

I am waiting for your valuable help. Thanks in advance for your time and explanations...
