Abstract
The invention is for an apparatus and method for pumping of electrically conductive liquids such as liquid metals and electrolytes. The apparatus of the present invention is a self-contained direct current (DC) magneto-hydrodynamic (MHD) pump assembly formed by an upper core assembly, lower core assembly, and a flow channel. The flow channel is formed when the upper core assembly and the lower core assembly are put together. Permanent magnets are used to produce magnetic field inside the flow channel. When the flow channel is filled with electrically conductive liquid, the liquid comes into contact with electrodes within the lower core assembly. The electrodes may be used to draw electric current through the liquid, thereby generating MHD force onto it. As a result, a pressure may be generated within the liquid and/or the liquid may be caused to flow.
