International Workshop on
Electromagnetic Boundary Layer Control (EBLC)
for Saltwater Flows
Dresden, July 7-8, 1997
Electromagnetic fields located on the surface of some immersed body allow
to introduce a Lorentz force distribution in the vicinity of the body
surface. It can be adapted to the fluiddynamical needs by suitably varying
the magnet and electrode configurations. This idea offers several control
possibilities for saltwater flows like
It is a very recent topic of fluiddynamical activities. A huge field of
applications can be expected. Presently the impression is that some
specific configurations have been tested, but a complete understanding is
still far away. The overall questions are:
- stabilization of the flow,
- suppression of flow separation,
- influence on near-wall turbulence,
- drag reduction and even thrust production.
The goal of the workshop is to assess the state-of-the-art in that field,
to stimulate the discussion between the involved teams, and to expose our
own research program to a critical, international discussion. Strong
emphasis will be placed on discussions among the limited number of
- Which Lorentz force distribution would give the optimal
effect for each fluiddynamical requirement?
- How can practically such an optimized Lorentz force
distribution be reached?
The workshop will focus purely on the fluiddynamical aspects of applying an
electromagnetic Lorentz force in the vicinity of a body for flow control.
Side problems like material questions or the design of an electromagnetic
thruster might be mentioned, but are not the focus.
The MHD group of
Research Center Rossendorf,
Germany, has been working in
many fields of liquid metal MHD for several years. Recently, a programme on
MHD effects in saltwater flows was started.
As an example of our activities in EBLC,
you can have a look at an
MPEG-movie (385 kB)
demonstrating the control of a cylinder wake. The
Lorentz forces F are fed into the boundary layer parallel to the
cylinder surface, the orientation of the forces and the direction
of the mean flow U are denoted by arrows in the upper left corner.
Since the number of participants is limited, early registration is strongly
recommended. There will be a registration fee of maximum 300,-DM.
The workshop is planned to last two days. There is an option for a third
day (i.e. July 9) depending on the number of submitted contributions, or a
visit of our laboratories just after the workshop.
|| The workshop will be held in Dresden (Germany).
