  2. 1. A Method for the Study of Unsteady Cavitation - Observations on Collapsing Sheet Cavities

    Author : Johannes Schöön; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cloud cavitation; re-entrant jet; cavitation erosion; gust generation; cavitation;

    Abstract : When subjected to sufficiently low pressures, water will eventually come apart. Gas-filled cavities appear in the water: it is said to cavitate. When the cavities collapse, they often do so quite vigorously, causing noise, vibrations and erosion. A well-known example of cavitation is that found on heavily loaded ship propellers. READ MORE

    Abstract : An operating marine propeller is one of the major sources inducing hull pressure pulses, onboard noise and vibration as well as underwater radiated noise. There are rising concerns of environmental impacts and comfort and welfare of passengers and crews due to these negative effects. READ MORE
