Abstract
A matrix in a rotating rotor prevents or inhibits formation of waves in a liquid ring. The matrix may be located in first and/or second channel sections defined by the rotor, liquid passing from the first to the second channel section; and a turbine may have a scoop removing liquid from the second section, proximate ends of barriers defined by the matrix. The matrix includes grooves between the barriers to communicate liquid generally parallel to an axis defined by the rotor. The grooves have end openings and may be closed in a direction toward that axis.
Claims17
Rotary apparatus comprising
- (a) a rotor having an axis and defining an annular channel to receive liquid that rotates with the rotor about the axis thereof,
- (b) a matrix in the channel for trapping the liquid in the matrix, thereby to inhibit surge wave development that otherwise is productive of rotor vibration during such rotor and liquid rotation,
- (c) the matrix including grooves to communicate fluid in a direction generally parallel to an axis defined by the rotor, the grooves having end openings and being closed in a direction toward said axis.
Rotary apparatus comprising
- (a) a rotor having an axis defining an annular channel to receive liquid that rotates with the rotor about the axis thereof,
- (b) a matrix in the channel for trapping the liquid in the matrix, thereby to inhibit surge wave development that otherwise is productive of rotor vibration during such rotor and liquid rotation,
- (c) said matrix comprising barriers spaced about the rotor axis and extending generally parallel to said axis,
- (d) and wherein an annular sub-channel is formed at corresponding ends of the barriers, to communicate liquid to grooves formed between the barriers,
- (e) said grooves communicating liquid in direction generally parallel to the rotor axis, the grooves having end openings at said sub-channel confined to rotate with said rotor.
