项目摘要

The measurement of flow velocities in hot and aggressive liquids such as liquid aluminium and molten glass constitutes one of the grand challenges of industrial fluid mechanics. A different, albeit physically closely related challenge is the detection of deeply lying flaws and inhomogeneities in electrically conducting solid materials. Since 2004, scientists and engineers at Ilmenau University of Technology have been at the forefront of the development of two novel techniques, termed Lorentz force velocimetry and Lorentz force eddy current testing, which promise to meet these challenges. Both techniques are based on measuring a minuscule Lorentz force, which acts upon a magnet system interacting with the moving liquid or solid. Based on the experience existing in Ilmenau in the fields of high-precision force measurement, high-resolution numerical simulation of fluid flows and the solving of inverse magnetohydrodynamic problems, the goal of the Research Training Group is to measure the Lorentz forces whose value is between 1e-11 N and 1 N, and to deduce the desired parameters in fluids and solids by solving inverse problems. In order to reach this goal, a symbiotic interaction of high-precision experiments and numerical simulations are planned in three fields, namely A - flow measurement in liquid metals, B - flow measurement in electrolytes, C - eddy current testing of solid materials. It is planned to use the research results in collaboration with industry to develop industrial prototypes, which can be commercialised outside the Research Training Group. The present subject is well suited for a Research Training Group since the different fields of application are connected with each other by three methodological groups, namely MB - magnet systems, KS - force measuring systems, and TS - theory and simulation. The educational programme is characterised by three unique aspects. (1) The graduate students will acquire specialised knowledge in the field of computational engineering. (2) They will be involved in project-specific international collaboration. (3) The graduate students will be encouraged to work in close contact with industry. By virtue of colloquia, an extensive visiting-scientist programme, brainstorming-meetings and regular monitoring, the students will be enabled to complete their PhD within three years.

测量液态铝和熔融玻璃等高温腐蚀性液体的流速是工业流体力学的重大挑战之一。另一个虽然在物理上密切相关的挑战是检测导电固体材料中深层的缺陷和不均匀性。自 2004 年以来，伊尔梅瑙理工大学的科学家和工程师一直站在洛伦兹力测速和洛伦兹力涡流测试这两种新技术开发的最前沿，这两种新技术有望应对这些挑战。这两种技术都是基于测量微小的洛伦兹力，该力作用于与移动的液体或固体相互作用的磁体系统。基于伊尔梅瑙在高精度力测量、高分辨率流体数值模拟和逆磁流体动力学问题求解等领域的经验，研究训练组的目标是测量数值在1e-11 N和1 N之间的洛伦兹力，并通过求解逆问题推导出流体和固体中所需的参数。为了实现这一目标，计划在三个领域进行高精度实验和数值模拟的共生互动，即A - 液态金属中的流量测量、B - 电解质中的流量测量、C - 固体材料的涡流测试。计划利用研究成果与工业界合作开发工业原型，并可在研究培训小组之外进行商业化。本主题非常适合研究培训小组，因为不同的应用领域通过三个方法组相互联系，即 MB - 磁体系统、KS - 力测量系统和 TS - 理论与模拟。该教育计划具有三个独特的方面。（1）研究生将获得计算工程领域的专业知识。（2）参与特定项目的国际合作。（三）鼓励研究生与产业界密切联系。凭借座谈会、广泛的访问科学家计划、头脑风暴会议和定期监测，学生将能够在三年内完成博士学位。
