【摘要】 用一元的方法对一离心压缩机的级进行了设计,并用CFD软件对设计结果作了三维流场数值模拟。分析了级中各部件的流动损失,重点研究了回流器的损失并对其做了改进。另外还对级中部分主要流动参数的等值线作了分析。更多还原

【Abstract】 A centrifugal compressor stage is designed with 1D method. The 3D flow field of the stage is simulated utilizing CFD software. Flow loss of every part of the stage is analyzed. The flow loss of return channel is emphasized and the return channel is improved after the research .In addition, contours of some main flow parameters in the stage are analyzed.更多还原
