Grahic Jump Location
Cross section of compressor blading at midblade height, showing typical instantaneous wake dispersion: SS=suction side, PS=pressure side, a=circumferential offset of stator leading edge from center of IGV wake street.
Grahic Jump Location

Grahic Jump Location
Temporal variation of ensemble-averaged turbulence level 〈Tu〉 (percent) on stator stagnation streamline at inflow measurement plane 55.7 percent axial distance upstream of stator leading edge; variation with stator loading and IGV clocking
Grahic Jump Location
Comparison of predicted T–S wave frequency and measured instability wave packet frequency
Grahic Jump Location
Top: quasi-wall shear stress record from a hot-film gage located at s*=0.3108 on the stator suction surface for the medium loading case. High-pass filtered signal amplified five times and superimposed. Darker shaded regions indicate turbulent flow; lighter shaded regions indicate instability wave occurrence. Bottom: modulus of the Morlet wavelet transform for the quasi-wall shear stress record. Hatching indicates frequency range under consideration by the detection algorithm.
Grahic Jump Location
Simultaneous quasi-wall shear stress records from five gages spanning s*=0.1825–0.4390 on the stator suction surface. High-pass filtered traces amplified five times and overlaid on each raw signal. Darker shaded regions indicate turbulent flow; lighter shaded regions indicated instability wave occurrence. Individual events from Fig. 5 are highlighted by dashed lines.
Grahic Jump Location
Ensemble-averaged intermittency (shading) and probability of instability wave occurrence (line contours). Dashed line indicates 10 percent probability contour for relaxing nonturbulent flow: (a) IGV wake street on rotor (a/S=0.00); (b) IGV wake street in passage (a/S=0.50)
