摘要
对采用不同收缩角无叶扩压器的同一离心压气机进行了数值模拟,并就收缩角对压气机性能影响进行了详尽分析,并结合流场分析得出了这些影响所对应的流动机理,为进一步提升该压气机性能及为以后离心压气机无叶扩压器的设计提供参考。
A centrifugal compressor with different convergence angle diffuser was simulated, the influence of convergence an- gle on compressor performance was analyzed in detail and finally the corresponding flow mechanism of influencing factors was acquired by combining the flow analysis, which brought the reference for designing centrifugal compressor vaneless diffuser and improving compressor performance.
