| Abstract: | The performance curves are important for evaluation of a compressor performance and significant for research on trends and formation mechanism.In the paper,a centrifugal compressor is simulated by a CFD software.The performance curves,especially the characteristics of these curves after the maximum efficiency point,are analyzed.Finally,the formation mechanism of these phenomenon is proposed.Those results provide a guidance for other researchers to understand the flow characteristics of the compressor. |
