Abstract
A compressor wheel having a hub and a plurality of impellers that define flow channels. At a restriction point downstream from an inducer-end and upstream from a point at which the flow channel turns from an axial flow to a radial flow, the impellers are thick-walled, and at that point a sum of the flow-channel restriction-point tangential dimensions is not greater than 50% of the circumference at the restriction point. The thick-walled impellers are formed with hollow cavities between pressure-side and suction-side walls. From the restriction point to an exducer, the sum of the flow-channels' tangential dimensions increases at least proportionately to the square of the radius from the axis-of-rotation.
