Abstract
An impeller of a centrifugal compressor includes: a plurality of blades each of which has a leading edge, a trailing edge, a pressure surface and a suction surface extending between the leading edge and the trailing edge, and a shroud-side end and a hub-side end defining the pressure surface and the suction surface together with the leading edge and the trailing edge. The pressure surface and the suction surface are each configured such that a blade element connecting the shroud-side end and the hub-side end is linear. The trailing edge is configured such that an outer diameter at the shroud-side end is larger than an outer diameter at the hub-side end, the trailing edge having a convex shape with respect to an imaginary straight line connecting the shroud-side end and the hub-side end in the trailing edge.
