Abstract:

The equipment purchased under this DURIP Equipment Grant was a 6.5 Tesla liquid helium-cooled superconducting magnet that was specially configured for studies of MHD flow control, power extraction, and thrust enhancement in supersonic air flows. The design of this magnet is unique in that the high magnetic field region lies at the center of a three-way cross. In the vertical direction, there is a two-inch diameter thru-hole to provide optical access or access to electrodes placed at the top and bottom of an MHD device. Each of the two horizontal directions are rectangular channels with approximately 3 x 3 clear access. This configuration provides the capability of installing external ionization devices that drive electrons along the magnetic field lines, which are orthogonal to the air flow path.
