Abstract

See full text

A hydraulic modulator provides a rectangular outlet from which water can be discharged across an outlet mouth. Spaced from the rectangular outlet across the outlet mouth is a rigid blade. Because water is effectively incompressible at the frequencies of interest a compliance chamber is provided along an interior side of the rigid blade. Mechanical compliance elements are provided within or adjacent to the compliance chamber which may be displaced to absorb and discharge mechanical energy from the flow of water. Water flow shifts back and forth relative to the interior and exterior sides of the rigid blade.
