N2 - This forum paper discusses phase-resolved turbulence measurements of the flow downstream of an axial turbine, and especially how phase-resolved measurements compare to time-resolved measurements. The time-resolved spectra produced higher velocity fluctuations than the corresponding phase-resolved spectra even when the periodic component was filtered out from the time-resolved measurements. The phase-resolved spectrum effectively removes all the peaks in the spectrum except for the ones associated with the blade-passage frequency.
