Hi everybody,
I'm dealing with simulation of turbomachine in OpenFOAM. I need the pressure field on the rotor in frequency domain for some vibrations analysis. So somebody told me that as the rotor is periodic, instead of doing FFT I have to do Fourier series decomposition to only get the relevant harmonics of the signal. My pressure is extracted at each revolution. so how do I do that ? For me I know just how to perform FFT but it for a broad of frequencies. Hope I have explain my problem. If somebody can help me clarify the matter may be I'm mistaken.... Thanks. Kossivi
