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.
