Boundary Layer Noise Source Model

Hi everyone.
I am trying to predict and measure noise due to vortex shedding off a circular cylinder and airfoil. I have used the Ffowcs-Williams and Hawkings (FWH) acoustic model and this to be relatively ok for the noise measurements at different recievers. However, I want to use the Broadband Noise Source Model and in particular the Boundary Layer Noise Source Model. However, I am unable to locate the option to select the BL noise model and can only access the Broadband model. The Fluent tutorial mentions the BL model and this would be great for measuring noise due to vortex shedding. So, I was wondering if anyone knows how to obtain the BL noise within Fluent through the Acoustics options? Are there certain parameters we must set? Thanks. |
