摘要:
An impeller for a centrifugal compressor is characterized in that a shroud side of a front edge 7a of a splitter blade 7 is disposed so as to be displaced toward a negative-pressure surface Sb of a full blade 5F from a position equidistant from the full blades 5R and 5F in a circumferential direction such that a blade-end leakage vortex generated during a high flow rate which occurs from a blade-end clearance between the tip of the full blade 5F and a shroud toward the portion of the front edge 7a of the splitter blade 7 gets over the front edge 7a of the splitter blade 7.
