Based on the meanline flow model and the optimization algorithm combining complex method with simulated annealing algorithm,an aerodynamic performance prediction and IGV-stator setting angles adjustment optimization method is proposed for multi-stage axial-flow compressors.The related Python codes are developed and applied to the first three-stage transonic axial-flow compressor NASA-74 A.The aerodynamic performance map and optimal IGV-stator setting angles are obtained.The results show that the proposed method is capable of predicting the aerodynamic performance map in good agreement with the experimental data,in particular,is capable of predicting accurately the surge boundaries at various speedlines.The IGV-stator setting angles adjustment optimization achieves significant improvement in the maximum adiabatic efficiency at each speedline.The work demonstrates the reliability of the proposed method and codes,and is of certain theoretical reference value and important engineering application significance for the development of advanced aerodynamic design system and adjustment technology for multi-stage highly-loaded axial-flow compressors.
