Resolving surface nanobubbles as cavitation nuclei

该项目旨在研究汽蚀的发生和控制，这是半个多世纪以来的一个具有挑战性的问题。空化是气泡生长和随后崩溃的过程，会对邻近表面造成噪音和损坏，例如船舶螺旋桨和阀门的故障。该项目预计将揭开空化核的神秘面纱，并开发出无空化设计，以减轻空化对螺旋桨和阀门造成的损坏，以及噪音。预期的结果将大大推进现有的流体物理前沿基础知识，为澳大利亚在海洋、泵和阀门行业提供显著的优势，并使澳大利亚的工业和经济显著受益。

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.
