摘要：

In this paper, wet compression effects on an eight-stage axial subsonic compressor is simulated by steady numerical methods. Special attention is paid to the compressor design operating condition and rotating stall boundary to contrast and analyze the changes such as the compressor performance and the flow field characteristics under dry and wet conditions. The motions of water droplets are also simulated and analyzed. The results indicate that wet compression could weaken or eliminate the flow separation, improve the flow capacity, efficiency and pressure ratio of this compressor and make the compressor operating near the rotating stall boundary enter into the normal working condition.
