【Abstract】 Aiming at the performance degradation and failure of compressors caused by particle fouling and erosion damage, the research progress of domestic and foreign research institutions in the influence of particle fouling and erosion damage on the performance of axial compressors in recent years was systematically summarized. Numerical simulation methods, experimental research methods and typical research conclusions about the compressor performance degradation mechanism and characteristics caused by fouling and erosion damage were emphatically introduced. Based on the current research hotspots and development tendency, further studies focus on the impact of particle fouling and erosion damage on the characteristic of axial compressors performance degradation were proposed. The interaction mechanism between the details of the unsteady flow field in the axial flow compressor cascades and the motion behavior of fine particles should be explored through refined numerical simulation and visualization experiment technology. Thus, the mechanism of compressor performance degradation caused by particle deposition and erosion damage could be revealed, and finally, quantitative relationship between particle deposition, erosion damage and compressor performance degradation should be established.
