The main objective of the project is to investigate the high-speed dynamics of micro-bubbles in liquids by numerical simulation. This topic is highly relevant for the development of novel techniques in medical, environmental, and bio-physical applications. The current project focuses on (i) the development of a three-dimensional model for high-speed-bubble dynamics, (ii) the development of an accurate interface model for cavitation bubble dynamics, (iii) the development of a numerical model which is capable of representing the interaction between free-gas bubbles and cavitation bubbles, and (iv) the validation of the developed models as reliable simulation environment for further research. The improvement in modeling and numerical prediction accuracy is expected to have a significant impact on quantitative analysis in complex multi-phase and multi-material applications.

该项目的主要目的是通过数值模拟研究液体中微泡的高速动力学。本课题与医学、环境和生物物理应用领域的新技术发展高度相关。目前的项目重点是(i)开发高速气泡动力学的三维模型，（ii）开发空化气泡动力学的精确界面模型，（iii）开发能够表示自由气泡和空化气泡之间相互作用的数值模型，以及（iv）验证所开发的模型作为进一步研究的可靠模拟环境。建模和数值预测精度的提高有望对复杂多相和多材料应用中的定量分析产生重大影响。
