Experimental studies are carried out at a low speed axial compressor with five different rotor/stator gaps. Analysis of the effect of axial spacing of two successive blade rows on the measured mean flow coefficient at stall inception and on the flow range of compressor under multi-cell rotating stall operating conditions proves that the stator can suppress the flow disturbance in the compressor and strengthen the stability of the compressor. Experimental data show that the stall flow coefficient decreases by...

Experimental studies are carried out at a low speed axial compressor with five different rotor/stator gaps. Analysis of the effect of axial spacing of two successive blade rows on the measured mean flow coefficient at stall inception and on the flow range of compressor under multi-cell rotating stall operating conditions proves that the stator can suppress the flow disturbance in the compressor and strengthen the stability of the compressor. Experimental data show that the stall flow coefficient decreases by reducing the axial spacing of successive blade rows. Moreover, by reducing the axial spacing, the stall pattern transition pace from multi-cell stall to single-cell stall can be shifted. And the compressor directly slips into single-cell stall at 21.0% C_Raxial spacing. By analyzing the pressure fluctuation closed to the surge line, it can be known that there exists an eigenfrequency where the amplitude of the oscillating pressure suddenly and dramatically increases as the compressor runs close to the surge line and this pressure disturbance is relevant to the compressor instability.

Investigated was the aerodynamic instability problem of an axial-flow compressor during throttling tests.A nonlinear correlation-integral method was employed to analyze static pressure signals along the compressor casing-wall surface.The results of the analysis indicate that correlation-integral values of the static pressure signals at a given point of the compressor stator passage casing-wall surface will undergo regular changes,depending on the engine operating conditions,and reflect the flow separation conditions at corresponding locations.The correlation-integral values of static pressure at various-stage stator channel casing-wall surface along the compressor flow passage can reflect the flow matching status at the blade tip of the various compressor stages under different operating conditions.The correlation-integral values of the static pressure of the compressor first stage stator casing-wall surface reflect the impact of the bleed valve's switching state on the rotor end-wall flow regime at intermediate and low-speed operating conditions.The study conducted by the authors indicates that the correlation-integral analysis regarding the above-mentioned static pressure signals can serve as a kind of effective means for monitoring and diagnosing the compressor aerodynamic stability.
