Abstract
This paper presents a design of the spiral winding-free MHD pump engineered to transport liquid metals and alloys. A distinctive feature of this pump is that it has a spiral channel. By changing the number of turns in the channel and by modifying the channel cross-section, the pressure drop--flow characteristics can be varied over a wide range. To generate an induction magnetic field, several ``electrical loop" arrangements have been considered. The pressure drop--flow characteristics of the pump have been determined in experiments with a gallium circuit. Figs 5, Refs 3.
