MEASUREMENT OF FLUID PROPERTIES FOR MAGNETOPLASMA-DYNAMIC POWER GENERATORS

Abstract

A closed loop MPD power generation device was designed, constructed, and operated. Two modes of operation were observed--saturating and nonsaturating. The saturating mode is associated with low seeding ratios while the nonsaturating mode is associated with high seeding ratios and high leakage resistances. During operation, leakage resistances varied between 0.1 and 1.0 megohms. Of the two modes observed, only the saturating mode was investigated thoroughly. The observations were made under the following conditions: pressure--slightly above atmospheric, Magnetic field--up to 21,500 gauss, Velocities--up to 250 m/sec at the channel entrance, Temperatures (static)--up to 1500K. For the saturating mode at these conditions, no nonequilibrium ionization was observed. Theoretical considerations indicate that to observe nonequilibrium ionization, runs should be made at lower pressures and higher velocities and temperatures than those stated previously.
