| Abstract: | Bleed pipelines, connecting the axial compressor and the turbine, are important components during the operation of the gas turbine. The compressed air is extracted from several certain stages of the compressor, and then, conducted in to corresponding stages of the turbine, for blade cooling or surge avoiding. This paper presents the investigation of flow fields in two consecutive compressor blade rows with the interstage bleed in between, and analyzes the effect of the bleed on the compressor performance. |
