RUI Chang-sheng, WU Hu. Study of staged propagation of circumferential steady total pressure distortion in axial flow compressors[J]. 2007, 22(12).DOI:
Based on the stage characteristics of axial flow compressor
a new model was established for calculating the propagation of circumferential steady total pressure distortion in multistage axial flow compressors.The inlet angle of attack
circumferential flow of stages and coupled compressor diffuser flow were also analyzed numerically.Meanwhile
the influences of axial attenuation of circumferential steady total pressure distortion
unsteady primary level and coupling performance of compressor outlet on the characteristic of compressor were discussed.Based on this model
the multistage axial flow compressors were analyzed numerically
proving that this model is reasonable and feasible.
