Numerical Modelling of Traveling Magnetic Field Stirrer for Liquid Lithium


Abstract

Thermally-activated chemical source of electric energy is one of the alternative sources of special purpose. Anodes for such batteries are made of lithium-boron composite. The use of electromagnetic stirring in the technology of production of such a material makes it possible to obtain a good quality distribution of boron powder in a lithium melt. As the source of the electromagnetic field used two inductor of the traveling magnetic field (TMF). TMF inductor system allows to generate a different flow pattern as one, two vortex or more tricky flow structure. The computations of mass transfer in the melt are performed using a three dimensional k-omega SST turbulence model. A 3D electromagnetic model was used for Lorenz force density computation. Coupling of proposed numerical model were performed by means of COMSOL Multiphysics.
