To investigate the influence and mechanisms of the diffuser on the aerodynamic performance of an advanced high-load axial flow compressor, a 2.5-stage high-load axial flow compressor coupled with a diffuser was selected as the research subject, using validated numerical simulation methods. A systematic and deep study was carried out on the impact and mechanism of the introduction of the diffuser and divergence angle distribution on the performance of the compressor/diffuser coupling matching. The results showed that the divergence angle distribution of the diffuser upper/lower wall can significantly affect the aerodynamic performance of the high-load axial flow compressor. Under a constant area ratio, as the divergence angle
