“…The fully coupled MHD solution for the waves and fluid flow is validated extensively for the case of a single interface in the aluminium electrolysis cells. The solution is compared to measurements of the velocity fields [7,8] and the wave frequencies [6]. The computed and measured wave frequencies are similar to the typical gravity wave frequencies, however the exact values are shifted due to the MHD interaction.…”

Liquid metal batteries are possible candidates for large scale energy storage offering a possible breakthrough of intermittent wind and solar energy exploitations. The major concern over their practical implementation is the operation at elevated temperatures and sensitivity to liquid motion. The concept of liquid metal battery bears a close similarity to aluminium electrolytic production cells. The two liquid layer MHD effects can be projected to the three liquid layer self-segregated structure of the batteries. This paper presents numerical models for the three density-stratified electrically conductive liquid layers using 3D and shallow layer approximation accounting for specific MHD effects during periods of battery activity. It is demonstrated that a stable operation of these batteries can be achieved if reusing an infrastructure of existing aluminium electrolysis pot lines. The basic principles of the MHD processes in the cells are illustrated by the numerical example cases.

“…The mass of the DX optimized potshell was reduced by 21 %; nevertheless, the strength was not decreased due to improved mechanical characteristics of the fully welded potshell when compared with the previous potshell using tack welded cradles and a bolted deckplate. This potshell was designed using mathematical models [9] and initially tested on one modified DX cell in DUBAL Potline 8 under the project name 'DX Step 1'. Subsequently the same design was used on the DX+ cells but with additional cooling fins than on the original DX standard and DX Step 1 cells.…”
