0966527ZikanovThe project is a part of the cooperation research activities conducted by the University of Michigan Dearborn, MI, USA and the Ilmenau University of Technology, Germany. It addresses the fundamental questions of interaction between flows of electrically conducting fluids and magnetic fields. Intellectual Merit:The project advances our understanding of flows of electrically conducting fluids affected by magnetic fields. The main attention will be given to typical technological and laboratory flows of liquid metals and oxide melts. Model flows in a rectangular duct will be used to investigate how the magnetic field affects the transition to turbulence and properties of turbulent flows, in particular, their ability to transport heat and admixtures. On the basis of the acquired understanding, the PI will search for optimal control methods of electromagnetic flow. Broader Impact:The results of the research are expected to advance the understanding, modeling, and optimization of the processing of electromagnetic materials, such as steel, aluminum, and semi-conductor crystals, as well as for the design of lithium cooling blankets for future nuclear fusion reactors. In all such technological processes, optimization of the field flow interaction is a key to reduction of energy consumption and environmental impact. The project will foster a competitive research environment and dynamic innovative instruction at the University of Michigan Dearborn, an institution focused on serving the metropolitan Detroit community. A graduate and several undergraduate students will be trained in the fields of turbulence theory, magnetohydrodynamics, and computational modeling. Close international cooperation strengthens the research and will establish new ties between the U.S. and German science communities. It also opens opportunities for students at the University of Michigan Dearborn to enrich their education via participation in international collaboration activities, visits to foreign research centers, and interaction with visiting German scientists.

0966527 Zikanov该项目是美国密歇根大学迪尔伯恩和德国伊尔梅瑙理工大学合作研究活动的一部分。它解决了导电流体和磁场之间的相互作用的基本问题。智力优势：该项目推进了我们对受磁场影响的导电流体流动的理解。主要注意力将放在液态金属和氧化物熔体的典型技术和实验室流程上。矩形管道中的模型流将用于研究磁场如何影响湍流的过渡和湍流的特性，特别是它们传输热量和混合物的能力。在此基础上，PI将寻求电磁流量的最优控制方法。更广泛的影响：研究结果预计将促进对电磁材料（如钢，铝和半导体晶体）加工的理解，建模和优化，以及未来核聚变反应堆锂冷却毯的设计。在所有这些技术过程中，场流相互作用的优化是降低能耗和环境影响的关键。该项目将在密歇根大学迪尔伯恩培养一个有竞争力的研究环境和充满活力的创新教学，这是一个专注于为底特律大都市社区服务的机构。一名研究生和几名本科生将接受湍流理论、磁流体力学和计算建模领域的培训。密切的国际合作加强了研究，并将在美国和德国科学界之间建立新的联系。它还为密歇根大学迪尔伯恩的学生提供了机会，通过参与国际合作活动，访问外国研究中心以及与来访的德国科学家互动来丰富他们的教育。
