Miniature dc electromagnetic pumps of heavy and alkali liquid metals at up to 500 °c for nuclear and industrial applications

Abstract

Provided are pumps for circulating heavy and alkali liquid metals at below 500° C. without active cooling. A direct current miniature and submersible electromagnetic (DC-EM) pump includes a rectangular flow duct, a pair of magnets located on opposing sides of the rectangular flow duct and a pair of electrodes located on opposing sides of the rectangular flow duct that do not have the magnets. When a current is applied to the electrodes, an electrically conductive fluid flows through the rectangular flow duct by using generated Lorentz forces in a direction perpendicular to the magnetic field flux density created by the opposingly located magnets and a DC electrical current created by the electrodes.
