<p><P>PROBLEM TO BE SOLVED: To provide an impeller of a centrifugal compressor, which avoids the interference of an inlet edge of a splitter blade with respect to a leaked swirl from a tip of an inlet edge of a full blade, and achieves a high pressure ratio and high efficiency, in an impeller of a centrifugal compressor with a splitter blade. <P>SOLUTION: The inlet edge 7a of the splitter blade 7 is positioned downstream of a leaked swirl line WL, in a flow direction of fluid flowing between full blades. The leaked swirl line WL is formed by connecting the center position P of a throat SR forming the minimum interval from the inlet edge 5a of a rear full blade 5R positioned on a rear side in the rotational direction of the impeller to a front full blade 5F disposed on a front side in the rotational direction disposed to be adjacent to the rear full blade 5R, with the inlet edge 5a of the full blade 5F. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
