Abstract
A free-surface liquid transfer apparatus for rotating machinery includes a stationary member. The stationary member includes a main surface configured to align to a rotating member, a landing surface arranged around the main surface configured to receive and slow a continuous film of working fluid transferred from the rotating member, an annular gap arranged around the landing surface, and a hollow torus cavity arranged proximate the annular gap configured to receive the slowed continuous film of working fluid transmitted through the annular gap.
