Unsteady fluids flows are common in the fields of technology, engineering and physiology. This project brings together a multi-disciplinary team to consider the issue of unsteady friction. The research will focus on understanding the behaviour of water in pipes when subject to very fast transient events (such as those which cause the common problem of water hammer in the home). The project will produce new results that will be used by water engineers to design improved techniques for the rapid non-invasive identification of leaks in underground pipelines. As such our research has the potential to contribute huge savings to Australia's increasingly valuable water resources.

不稳定流体流动在技术、工程和生理学领域很常见。该项目汇集了多学科团队来考虑不稳定摩擦问题。该研究将重点了解管道中的水在遭受非常快的瞬态事件（例如导致家庭中常见的水锤问题的事件）时的行为。该项目将产生新的成果，水工程师将利用这些成果来设计改进的技术，以快速非侵入性地识别地下管道的泄漏。因此，我们的研究有可能为澳大利亚日益宝贵的水资源节省大量资金。
