Abstract:
1. A bearing assembly configured for use in turbines and pumps, the bearing assembly comprising: a shroud that is configured to rotate around a central axis; a disk seated in a recess in the shroud so that the disk is configured to rotate with the shroud, the disk being oriented perpendicular to the central axis, wherein the recess comprises a cavity proximate to an outer face of the recess, and an interior surface of the recess between the cavity and the central axis is substantially planar and perpendicular to the central axis; and a stationary element disposed adjacent to the shroud, wherein at least one surface of the disk is configured to contact a fluid so that when the disk rotates, the at least one surface of the disk resists the generation of drag between the at least one surface and the stationary element of the bearing assembly.
