Abstract
An inducer having a hub and a plurality of blades is provided. In one embodiment, the thickness of the blades is defined such that during the operation of the inducer each of the blades is positioned underneath a cavitation vapor line so as to improve the performance of the inducer. In another embodiment, the hub is contoured or ramped according to a fifth order polynomial to provide improved performance. In another embodiment, the flow passage area of the inducer, as taken normal to the flow of fluid, is varied according to a fifth order polynomial to provide improved performance.
