探针支杆对离心压气机性能影响的研究OA

With a probe radius rod being added at the inlet of the centrifugal compressor,the research looks into its influence on the aerodynamic performance of the compressor,and calculates the characteristic lines of the centrifugal compressor with probe radius rods of different blockage ratios,axial positions,and shapes.The results show that compared to the working condition without probe radius rod,the characteristic line of the compressor with probe radius rod is generally shifted to the lower left,that the larger the blockage ratio of the probe support in the flow channel,the more severe the performance degradation of the compressor,that the axial position of the probe radius rod has little effect on the compressor characteristic line,and that when the blockage ratio stays the same,the performance of the compressor with water-drop-shaped radius rod is improved compared to the cylinder-shaped support,and the compressor works best when the diameter ratio of the front and tail edges of the water-drop-shaped radius rod is 5∶3.
