What is The Stochastic Structure Of Downstream Pressure From An Axial Compressor—ii. An Investigation Of Blade-to-blade Variability about?
This work investigates the use of statistical and time-frequency analysis of the downstream pressure signature to characterise blade-to-blade variability of both average and residual pressure associated with a single row 36 blade axial compressor. Analysis of the average pressure signatures suggests that the blade mean pressure signatures are not identical at a 90% significance level. Analysis of the residual signatures, obtained by removing the average signatures, reveals that the wake region contains approximately four times as much power as the core flow region. Time-frequency analysis shows that the strong harmonic content which persists in the residual process is temporally concentrated in the wake flow region, but that the blade-to-blade variability of this narrowband structure is sufficient to be almost eliminated upon averaging of individual blade spectra.
