Abstract
A free-surface liquid transfer apparatus for rotating machinery includes a rotating member. The rotating member includes a main shaft defining a hollow inner cavity, an outer cylindrical wall defining a hollow annular cavity in fluid communication with the hollow inner cavity through a plurality of orifices formed on the main shaft, and a slinger formation in fluid communication with the hollow annular cavity through a plurality of radial slots formed through the slinger formation. A central axis of the main shaft, a central axis of the hollow annular cavity, and a central axis of the slinger formation are collinear, and the slinger formation is configured to transmit working fluid received through the plurality of radial slots outward as a continuous film having both tangential and radial velocity components.
