Bleeding impact on performance of transonic axial compressor

  • By analyzing the transonic single-stage compressors NASA Stage35, multiple bleeding plans were presented according to the physical phenomena of the flow in rotor and stator passage. Combined with experimental results, compressor flow field with and without air bleeding were compared to study the impact of the rotor casing bleeding position and the stator casing bleeding amount on the compressor flow field and performance. The results show that rotor casing bleeding can inhibit the development of tip leakage flow in the passage circumferential, reduce the flow loss of the tip region and enhance the compressor performance. The impact mechanisms on the tip flow field vary as the bleeding positions and structures change. Stator casing bleeding can cut the flow loss and improve the compressor efficiency.
