Abstract

An impeller includes a body with an interior channel extending through the body along a centerline axis of the impeller. A plurality of blades is connected to the body on a forward end of the impeller centerline axis. The plurality of blades surrounds the interior channel and is fluidly connected to an array of inlets. An array of pentagonal channels extends through the body and radially outward in a spiral pattern. Each pentagonal channel is fluidly connected to a corresponding vane inlet and a corresponding pentagonal-shaped outlet. Each channel maintains a pentagonal cross-section shape from the inlet to the outlet. Each downward-sloping face of the cross section is more than 35 degrees from a horizontal plane perpendicular to the centerline axis of the impeller.
