Abstract: A shrouded impeller includes an impeller having a plurality of blades and configured to rotate about an axis, and a shroud disposed adjacent to the impeller and configured to corotate about the axis with the impeller and translate axially relative to the impeller. A method of varying a geometry of a flow area of the shrouded impeller includes rotating the shroud and the impeller about the axis and axially translating the shroud relative to the impeller to increase or decrease a rate of flow between the shroud and the impeller.
