Cavitation tunnel characterized by stable cavitation-nuclei-distributions.

Cavitation inception from bubble nuclei.

The tensile strength of ordinary water such as tap water or seawater is typically well below 1 bar. It is governed by cavitation nuclei in the water, not by the tensile strength of the water itself, which is extremely high. Different models of the nuclei have been suggested over the years, and experimental investigations of bubbles and cavitation inception have been presented. These results sug...

Hydroacoustic Characterisation of the AMC Cavitation Tunnel

This paper presents recent results from an Industry-University-Defence collaborative project whose aim is to characterise the hydroacoustic environment of the Australian Maritime College Cavitation Tunnel. After summarising the operation of the tunnel, a methodology for measuring and processing the hydroacoustic measurements is presented that includes a technique for reducing the level of turbu...

Investigating to Cavitation Behavior of Orifice Tunnel

Strong velocity scale effect on cavitation for orifice tunnels was revealed through comparing the results of model tests in vacuum tanks and that of prototype measurements at construction site. A new formula predicting incipient cavitation number of orifice rings is presented in this paper. The predicted data for the prototype scale are coincident well with the prototype measured one.

Reflections on cavitation nuclei in water

Cavitation Nuclei Population and Event Rates

To model the processes of cavitation inception, noise and damuge, it is necessaty to generate a model of the cavitation event rate which can then be coupled with the consequences of the individual events to produce a complete synthesis of thephenomenon. In this paper we describe recent efforts to connect the observed event rates to the measured distributions of cavitation nuclei in the oncoming...
