A COMPARISON OF MAGNETIC SYSTEMS FOR PRODUCING STRONG LARGE-VOLUME FIELDS,
Abstract
Four types of magnetic systems are analyzed and compared with regard to their suitability for use in large-scale MHD power generators. The four types discussed are: (1) an ironless coaxial magnetic system with a tangential field, (2) an ironless elliptical-type system with a winding in the form of two intersecting ellipses or circles, (3) an O-shaped system with a magnetic circuit, and (4) a diamond-shaped system with a magnetic circuit. The tabular data show the advantages of the elliptical system over the others for the whole range of the excitation energy, which is a function of the relative thickness of the current layer. The diamond-shaped system is preferred, however, if losses can be reduced by reducing the resistivity of the winding material. In the magnetic systems analyzed, excitation losses amount to about 10% of the generated energy, provided the MHD generator is sufficiently large.
