  impeller passage
Experimental investigation of the internal flow field of rotating impeller passage with inlet box
      
Using PDA and its measurement system, the flow fields at the different peripheral locations of rotating impeller passage of a diagonal fan with inlet box are measured.
      
The results are compared with the flow field of the rotating impeller passage of the same fan without inlet box.
      
The periodic unsteadiness is due to the distortion of the flow in the peripheral direction at the exit of the centrifugal compressor impeller, caused by the jet-wake type of flow discharging from each impeller passage.
      
It is revealed that impeller A achieves higher effective head than impeller B even though the flow patterns in impeller A are more complex, exhibiting secondary flows and reverse flows in the impeller passage.
