Abstract
In this work, we consider an MHD pump generating a travelling magnetic field. It consists of six C-shaped inductors located one after another. A flat channel for pumping liquid metal is placed in the gap between the inductors. The cores are fed by the alternating current from a three-phase source and are connected in such a way as to provide the generation of a travelling wave. Due to the pump design, the electrical windings in such a pump are located at a safe distance from the heated channel with liquid metal. The channel can be quickly removed and placed back into the pump. The paper presents results of experimental and numerical investigations of the temperature regimes and numerical simulation of magnetic fields in the ferromagnetic cores of the pump inductor. Numerical computation has been done to evaluate the electromagnetic volume forces, acting on the transporting channel. The pressure drop--flow rate characteristics of the pump have been obtained for a gallium circuit. The workability of the pump has been tested in liquid magnesium.. Figs 7, Refs 1.
