High-temperature liquid-metal MHD generator experiments
Abstract
Detailed data were obtained for the world's first high-temperature two-phase liquid-metal MHD generator under open-circuit conditions. Both single-phase (sodium) and two-phase (sodium and nitrogen) flows were used in the temperature range of approximately 490 to 740 K. The data presented includes pressures, voltages, and slip ratios (ratio of gas velocity to liquid velocity). The two-phase pressure-gradient data were well predicted by a simplified two-phase MHD correlation that includes the effect of a pure-liquid shunt layer between the electrodes. The slip ratio is shown to decrease with increasing temperature, implying higher generator and system efficiencies.
