Hi,
I am trying to convert discrete Fourier transform of pressure signal(monitor point in rotating reference frame) to stationary frame. I have the pressure(rotating frame) Vs time data and also the circumferential variation of pressure at each time point. Can anyone advise on how to convert the fft of pressure (rotating frame) to stationary frame. Or understand the rotating speed of the instability in stationary frame from unsteady CFD data done in rotating frame? thanks, |
