FFT & Pressure
I am using Fluent LES with point monitoring to capture the unsteady pressure effects in the near wake of a stator blade.
I have written all the data to a file, but now I need to analyze it. My question is not specific to Fluent. The data may be analyzed in another software like MATLAB.
But I am confused as how I should present and obtain my results. Should I take the time depended pressure data and apply an FFT. In my plot, do I plot pressure vs. frequency, or power vs. freq (what is exactly meant by power), I am a bit confused here.
Please help if you can... thanks!
