摘      要：Extensive numerical investigations of the performance and flow structure in an unshrouded tandem-bladed centrifugal compressor are presented in comparison to a conventional *** characteristics are explored for various tip clearance levels,axial spacings and circumferential *** impeller was modified to tandem-bladed design with no modifications in backsweep angle,meridional gas passage and camber distributions in order to have a true comparison with conventional *** degradation is observed for both the conventional and tandem designs with increase in tip ***-equation models for correlating stage characteristics with tip clearance are *** two designs,it is clearly evident that the conventional design shows better performance at moderate flow ***;near choke flow,tandem design gives better results primarily because of the increase in throat *** point flow rate also seems to drop for tandem compressor resulting in increased range of operation.
