  • DAMAGE TOLERANT CAVITATION NOZZLE
    Publication number: 20240001509
    Abstract: A cavitation nozzle is disclosed, including a plate, a hollow body, and a cap removably engaged with the hollow body and holding the plate against a distal end of the hollow body. The plate may have a central aperture and a distal surface, wherein the distal surface is bisected by a groove and the hollow body is configured to deliver high pressure fluid through the central aperture. The delivered high pressure fluid may be discharged as a cavitating jet.

  • Closed chamber abrasive flow machine systems and methods
    Patent number: 11577355
    Abstract: Systems and methods are provided for viscous and/or chemically erosive flow machining of work pieces. In certain examples, a tool for flow machining may be disclosed. The tool may include a cavity configured to receive a work piece and one or more inlets and outlets for viscous media flow. Viscous media and/or chemically erosive media can be flowed into the cavity and, via a media flow path, can be used to machine the work piece.
