International Workshop

Collaborative Research Center SFB 609
"Electromagnetic Flow Control
for Metallurgy, Crystal Growth
and Electrochemistry"



International Workshop on

"Flow Control by Tailored Magnetic Fields (FLOWCOMAG)"

Dresden, April 1 - 2, 2004

Electromagnetic fields provide a tool to influence the flow and, in turn, the head and mass transfer in electrically conducting fluids. An attractive feature for metallurgical or crystal growth applications is the contact-less form of this control. There have been many studies in the past analyzing the changes in the transport phenomena which take place by application of some type of magnetic field. In general, steady magnetic fields suppress flows and alternating magnetic fields drive some motion. The variety of magnetic field actions is very big which allows for an inverse approach: a pre-defined flow control is possible by tailored magnetic field systems. There is a basic fluiddynamic interest in such type of flow control, but applications in crystal growth, solidification, metal casting, welding and others are very close, too. Examples for such tailored flow control by magnetic fields should be presented at the workshop.
On the other hand, there is a growing community dealing from a theoretical and computational point of view with optimization, optimal or sub-optimal control and flow control in general. We expect that Magnetohydrodynamics (MHD) establishes an interesting example for it as it provides an active, well-controllable influence on the flow which can directly be tested in experiments. Hence, another important goal of the workshop is to establish a bridge between the optimization/control community and MHD.

Invited lectures will be given by John Kim, Max Gunzburger, George S. Dulikravich, Haecheon Choi, Nicholas Zabaras and Alessandro Bottaro.

Venue: The workshop will be held in Dresden (Germany) and is planned to last two or three days depending on the number of contributions. A visit of the MHD laboratory at FZD will be included. Note, during March 29-31, the is the "European Conference on Computational Optimization" takes place in Dresden (EUCCO 2004)

Organizers: G.Gerbeth, M.Hinze, G.Mutschke, F.Stefani
