Nucleation and Cavitation Inception in Tip Leakage Flows
Abstract
Predicting and delaying cavitation inception is critical to the stealth of undersea operations. The proposed research is unprecedentedly comprehensive and innovative in that the phenomenon of cavitation inception will be studied in detail using a holistic approach wherein several different aspects of cavitation inception, such as the effects of scale (Reynolds number), geometry, inflow, and nuclear content, will be looked at concurrently using a combination of visual, optical, and acoustic probes with precise control of dissolved gas and nuclei content distribution in the water tunnel. The outcome of the research will help answer many unresolved questions and issues regarding the cavitation inception on full-scale ships. The PI and his team are world-leading experts in the experimental research for measuring and diagnosing the fundamental physics underlying cavitation, with demonstrated credentials in the field and numerous publications in peer-reviewed top journals. For many years, they have developed and successfully operated a very unique variable water tunnel facility at the Australian Maritime College (AMC) Cavitation Research Laboratory. Their facility allows detailed measurement and diagnosis of the cavitation dynamics from its inception to collapse with the aid of their state-of-the-art" experimental apparatus and unmatched ability to create nuclei with ""designed"" population distributions. With a close tie and colla"boration with DST of Australia, the PI received a multi-million dollar research grant from the Australian Navy in 2018.
