Aero Acoustic - Postprocess-FWH Model- Octave Band

February 8, 2008, 16:26

Hi Everyone

I am trying to carry out an aeroacoustic simulation using FWH model. During post processing when I plot the Sound Pressure Level(SPL) for the Octave band Frequencies using Fourier Transformation panel, only SPL corresponding to octave frequencies 16.5Hz to 500Hz is plotted. Generally it should be form 16.5 Hz to 16000Hz. Kindly help.

Thanks

Manoj

Hi, Kumar.
How is your aeroaccoustic simulation? I like to simulate acoustic by using Fluent, but I don't know where to start.

Thank you.

Hi andi,

Any luck with your acoustics ? if you have finished do you know how to calculate 1/3 octave band of a particular set of frequency vs SPL values

Thanks,
Hasan K.J
