Abstract:

The disk represents a magnetohydrodynamic MHD channel geometry in which either a simple outward radial flow occurs, or there is a combination of radial flow with swirl. Distinguishing features and major advantages of the disk are electrodeless walls, and the simplicity of channel and magnet design. For airborne applications of the MHD generator, the goal is to achieve high power density and high power per unit weight. For certain electrical loads, a high voltage output is also desirable. The disk is uniquely suited to airborne applications because the radial symmetry peculiar to the geometry, and its capability to operate at very high electric fields, makes the disk a compact, high-voltage power supply. Described in the report is an experimental program concerned with the investigation and demonstration of the high-interaction performance of a large-scale disk generator driven by a large diameter 61.0 cm shock tube.
