This project aims to investigate the onset and control of cavitation, a challenging problem for over half a century. Cavitation is a process of bubble growth and subsequent collapse, and causes noise and damage to adjacent surfaces, e.g. the failure of ship propellers and valves. This project expects to unravel the mystery of cavitation nuclei, and to develop cavitation-free designs to mitigate the cavitation caused damage to propellers and valves, and noise. The anticipated outcomes will significantly advance existing fundamental knowledge at the forefront of fluid physics and provide Australia with a significant advantage in the marine, pump and valve industries, and significantly benefit the Australian industry and economy.

本计画旨在探讨空蚀的发生与控制，这是一个超过半个世纪的挑战性问题。空化是气泡增长和随后破裂的过程，并对相邻表面造成噪音和损坏，例如船舶螺旋桨和阀门的故障。本计画期望能解开空泡核之谜，并发展无空泡设计，以减轻空泡对螺旋桨及阀门造成的损害，以及噪音。 预期的成果将大大推进流体物理前沿的现有基础知识，并为澳大利亚在船舶，泵和阀门行业提供显着优势，并显着有利于澳大利亚的工业和经济。
