| Summary: | An improved integral method is proposed and developed
for the quantitative prediction of distorted inlet flow
propagation through axial compressor. The novel integral method is
formulated using more appropriate and practical airfoil
characteristics, with less assumptions needed for
derivation. The results indicate that the original integral method
(Kim et al., 1996) underestimated the propagation of inlet flow
distortion. The effects of inlet flow parameters on the
propagation of inlet distortions as well as on the compressor
performance and characteristic are simulated and analyzed. From
the viewpoint of compressor efficiency, the propagation of inlet
flow distortion is further described using a compressor critical
performance and its associated critical characteristic. The
results present a realistic physical insight to an axial-flow
compressor behavior with a propagation of inlet distortion. |
