离心压缩机叶片扩压器叶片安装角对旋转失速影响的实验

Effect of the Impeller Mounting Angle on Rotating Stall in a Centrifugal Compressor with Vaned Diffuser

用高频响的动态压力传感器及热线探针对叶片扩压器申的流动进行了探测,研究了叶片扩压器不同叶片安装角时失速参数的变化,并研究了转速对旋转失速的影响。

The flow in the vaned diffuser was measured by fast response dynamic pressure transducers and hot wire. The change of stall parameter in vaned diffuser is studied when the impeller mounting angle is different, and the effect of rotating speed on rotating stall is studied.
