项目摘要

The occurrence of interfaces, i.e. material or geometric frontiers between regimes with different physical properties not a priori prescribed, arises in an enormous number of inherently nonlinear problems from fluid-solid mechanics and financial mathematics to materials science and glaciology. The study of interfaces encounters, in addition to the presence of a free boundary, several other challenging aspects and complexities, including a physically proper description of the dynamics of three-phase contact lines, fluid motion over substrates with complex geometry, concentration-dependent physical properties, the presence of nanoparticles and phase transitions. We refer to these as complex interfacial phenomena (CIPh).The proposed research is a synergistic approach combining state-of-the-art modelling, simulations and experimentation to scrutinise a number of open problems and research directions in the area of CIPh. The aim is to rationally understand and systematically predict their physical behaviour and properties. This in turn will allow for step improvements to the performance and efficiency of a host of technologies and applications that rely crucially on CIPh. The theoretical-computational work will be complemented by detailed small-scale experiments that will act so as to verify the efficacy of the developed models, as well as aiding the development of a toolkit for practical applications. The work will be undertaken by a team from the Chemical Engineering and Mathematics Departments at Imperial College London with complementary skills and strengths.

界面的出现，即具有不同物理性质的制度之间的材料或几何边界不是先验规定的，出现在大量的固有的非线性问题，从流体-固体力学和金融数学到材料科学和冰川学。除了自由边界的存在外，界面的研究还遇到了其他几个具有挑战性的方面和复杂性，包括三相接触线的动力学的物理正确描述，具有复杂几何形状的基底上的流体运动，浓度依赖的物理性质，纳米颗粒和相变的存在。我们称之为复杂界面现象（CIPh）。所提出的研究是一种协同方法，结合了最先进的建模，模拟和实验，以审查CIPh领域的一些开放问题和研究方向。目的是合理地理解和系统地预测它们的物理行为和性质。这反过来又将允许逐步改进关键依赖于CIPh的许多技术和应用程序的性能和效率。理论计算工作将得到详细的小规模实验的补充，这些实验将验证所开发模型的有效性，并帮助开发实际应用工具包。这项工作将由伦敦帝国理工学院化学工程和数学系的一个团队承担，他们具有互补的技能和优势。
