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

2. Influence of Acoustic Interaction between Cavities That Generate Cavitation Noise
Abstract : The thesis concerns high frequency cavitation noise generated by marine propellers, for example. The collapse of a cavity is forced by the surrounding pressure which comprises the pressure in the undisturbed flow, the pressure disturbance associated with the local non-cavitating flow and, finally, the pressure disturbance from the presence and motion of neighbouring cavities.

3. Computational Modelling for Cavitation and Tip Vortex Flows
Abstract : Cavitation often brings negative effects, such as performance degradation, noise, vibration, and material damage, to marine propulsion systems, but for optimum performance, cavitation is almost inevitable. Therefore, it is necessary to better understand cavitation in order to maximize the performance without encounter- ing severe problems. READ MORE
