| Abstract: | stage-by-stage compression system model for predicting aerodyamic stability in multistage axial compressors with inlet dynamic pressure distortion is given in this paper. Based on dynamic static pressure variations, a method of recognition of predicting aerodynamic stability is developed. Numerical results of a three-stage experimental axial compressor are given by using thismethod. The critical positions of inlet total pressure fluctuations are determined. The quantitive relationships between inlet total pressure fluctuations and the surge time are obtained. The initial stage inwhich the flow in-stabilities first occurring is indicated. |
