Effect of innovative cathode on bath/metal interface fluctuation in aluminum electrolytic cell
A three-dimensional transient magnetohydrodynamic model has been developed to investigate the effect of innovative cathode on interface fluctuation of bath/metal in aluminum electrolytic cell.A homogeneous multiphase flow model of three phases including molten aluminum (metal) and molten cryolite (bath) using the volume of fluid (VOF) approach is used to describe phases interaction.Moreover, the electrical potential method is adopted for the electric current and magnetic field.The Electromagnetic force is recalculated at each time step and then is implemented in the momentum equation of bath and metal as a source term.Then the mathematical model is employed to investigate the effect of the innovative cathode on the electric current, magnetic field, flow field, and bath/metal interface fluctuation.The results show that the interface fluctuation would be suppressed with the help of innovative cathode.In addition, the gas bubbles also float up more quickly which is good to energy saving.
