Numerical Study of the Impact of Rotor Casing Bleeding Structure on the Performance of An Axial Compressor
By studying the single-stage and low-speed axial compressor, the function of the compressor throttle plug is simulated by using the moving mesh to get a time-accurate numerical simulation on the compressor overall performance. Combined with experimental results, compressor flow field with and without air bleeding are compared to study the impact of different bleeding structures on compressor performance. The results show that casing bleeding can ease the blockage generated by the tip leakage flow. As a result, outlet deviation angle and relative total pressure loss of rotor are significantly decreased in the tip region. The compressor performance will be improved and the stall will be effectively postponed. The number of stall cells varies as the bleeding structure change. And the more the number of stall cells, the smaller range and strength of the stall cells
