SFB 609: Electromagnetic Flow Control in Metallurgy, Crystal Growth and Electro Chemistry

热流体动力学和电动力学之间的连接环节是磁流体动力学。热流体动力学是将传热传质与流体动力学耦合起来的学科。在所涉及的流体是导电的情况下，电磁体积力被认为在力平衡中具有主要影响。电磁相互作用的这一部分由电动力学描述。两个研究分支，热流体力学和电动力学的耦合，评估流体动力学的电磁影响流的分析，控制和优化的方法。其应用可在冶金、晶体生长和电化学中找到。MFD合作研究中心的主题是电磁场对导电流体中流动和传输现象的直接影响以及对各种技术领域的适用性的基础研究。一般来说，所提出的处理方法是认识到电磁场对导电流体的非接触控制和影响所暴露的流动物理学的基本现象。在这些流动控制的逆过程中，也考虑了流动对电磁场的给定反馈。该工作领域为基础研究开发了具体的方法，而通过这种流动控制的逆方法，各种流动都是可行的，并可用于实验室实验。利用静态磁力，可以抑制流场，或者通过施加交变场，可以产生流场。这些陈述特别适用于具有高电导率的流体，如流体金属，但它们也适用于电化学中电解质中的弱传导。在此基础上，我们的目标是与科学合作伙伴一起渗透到技术应用中，这将带来很高的价值。这包括基础研究和工业应用之间的短期联系的良心。

The connecting link between thermofluiddynamics and electrodynamics is magnetofluid dynamics. The field of thermofluiddynamics couples the heat and mass transfer with fluid dynamics. In case the involved fluids are electrically conducting, the electromagnetic volume forces are considered to have a major influence in the force balance. This part of the electromagnetic interactions is described by electrodynamics. The coupling of the two research branches, thermofluiddynamics and electrodynamics, evaluates for fluid dynamics the analysis of eletromagnetically influenced flows, the ways of controlling and optimization. Applications may be found in metallurgy, crystal growth and electrochemistry. Subject of the collaborative research centre for MFD is the fundamental research for the direct influence of electromagnetic fields on the flow and the transport phenomena in electrically conducting fluids as well as the applicability for various technology areas. The proposed treatment in general is to recognize the basic phenomena of the flow physics exposed to non-contact controlling and influencing of electrically conducting fluids by electromagnetic fields. In these inverse processes of flow control a given feed back of the flow on the electromagnetic fields is considered as well. This working field develops specific ways for a basic research, while by this inverse method of flow control various kinds of flows are made feasible and accessible to laboratory experiments. With static magnetic forces flow fields can be suppressed or by application of alternating fields they can be generated. These statements are valid especially for fluids with high electrical conductivity like in fluid metals, but they are also of interest for a weak conduction in electrolytes in electrochemistry. Based on that, the aim is to penetrate with scientific partners into technical applications, which promise a high estimation of the value. This includes the conscience of short connections between basic research and industrial applications.
