| Abstract: | This paper presents two-dimensional unsteady numerical simulation of total pressure inlet
distortion coefficient (DC) and the characteristic of an axial compressor for square wave circumferential
total pressure inlet distortion. The distortion coefficients of different flow rates and different inlet
distortion generators are calculated and compared. The characteristics and stall points of different
DC are simulated while outlet condition of the compressor is gradually adjusted. |

| Keywords: | total pressure inlet distortion distortion coefficient (DC) stall margin numerical simulation |
