The IGV-impeller gap barely influences the compressor stage performance, but small gap leads to large pressure pulsation inside the flow field.
叶排间距大小对级性能影响几乎可以忽略,但间距减小会造成流场内压力波动增大;
A centrifugal compressor stage is designed with 1d method. The 3d flow field of the stage is simulated utilizing CFD software.
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。
The overall performance for NASA 37 low-aspect ratio compressor stage at 70% design rotating speed was obtained and the internal flow fields at typical operating conditions were emphatically analyzed.
This paper presents a numerical study on the performances of a compressor stage under different circumferential positions of the rear blades of tandem stator.
