TURBOMACHINERY AND METHOD OF MANUFACTURING THE SAME

摘要

An impeller (6) in a turbomachinery has blades (3) designed such that reduce d static pressure difference .DELTA.Cp between the hub (2) and the shroud (4) on the suction surface (3c) of the blade (3) shows a remarkably decreasing tendency near the impeller exit (6b) as it approaches the impeller exit (6b) between the impeller inlet (6a) and the impeller exit (6b).
