Clarity for the Cavity: a Framework for Acoustic Cavitation Measurement and Reporting

空化(超声驱动的气泡活动)在医疗和工业领域有着广泛的应用。然而，目前还没有测量和报告空化的框架，这意味着科学文献不一致，很难比较不同群体的研究。目前的问题包括机械指数等指标的使用超出了它们的限制，而且缺乏适当的分类系统意味着空化通常被归类为稳定的或惯性的，几乎没有科学依据。我的项目的目的是开发一个有科学依据的框架，解决这些问题，并允许在一系列医疗和工业应用的类似研究之间进行有意义的比较。为了做到这一点，我将在实验中研究具有代表性的空化的许多类型。具有并行声学监测的高速成像将有助于确定对声空化信号的基本理解，从而能够对当前的做法进行关键分析并提出新的做法。我希望与Precision Acoustics Ltd合作，与英国标准协会(BSI)超声波委员会分享我的发现，并为确保空化研究更一致的国际标准做出贡献。

Cavitation (ultrasonically driven bubble activity) has a variety of applications in the medical and industrial sectors. However, there is currently no framework for the measurement and reporting of cavitation which means that the scientific literature is inconsistent, and it is difficult to compare studies from different groups. Current issues include metrics, such as the mechanical index, that are being used beyond their limitations and a lack of a proper classification system means that cavitation is often categorised as either stable or inertial with little scientific reasoning. The aim of my project is to develop a scientifically grounded framework that will tackle these issues and will allow for meaningful comparison between similar studies over a range of medical and industrial applications. To do this, I will study many types of cavitation in experiments that are representative of the applications. High-speed imaging with parallel acoustic monitoring will help determine a fundamental understanding of the acoustic cavitation signal, which will allow for the critical analysis of current practices and propose new ones. In partnership with Precision Acoustics Ltd, I hope to share my findings with the British Standards Institute (BSI) committee on ultrasonics and contribute to international standards that will ensure more consistency in cavitation research.
