Abstract
A machine that includes a centrifugal impeller and a diffuser. The impeller has two rows of impeller blades. A first row accelerates the flow away from the axis of rotation, and discharges the flow in an outward radial direction to a second row of impeller blades. The second row first accelerates the flow toward the axis of rotation in an inward radial direction, and then accelerates the flow in the first axial direction. The diffuser has two rows of diffuser blades. A first row of diffuser blades first accelerates the flow in the first axial direction, and then accelerates the flow toward the axis of rotation. The second row of diffuser blades first accelerates the flow away from the axis of rotation, then accelerates the flow in the first axial direction, and then discharges the flow from the diffuser in the first axial direction.
