Abstract

An impeller (6) in a turbomachin-ery has blades (3) designed such that re-duced static pressure difference .DELTA.Cp be-tween the hub (2) and the shroud (4) on the suction surface (3c) of the blade (3) shows a remarkably decreasing tendency in the vicinity of the impeller exit (6b) as it approaches the impeller exit (6b) be-tween the impeller inlet (6a) and the im-peller exit (6b).
