1. A Method for the Study of Unsteady Cavitation - Observations on Collapsing Sheet Cavities
Sammanfattning : 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. LÄS MER
2. Numerical prediction of propeller induced hull pressure pulses and noise
Sammanfattning : 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. LÄS MER
