Abstract

We study liquid metal free surface deformation in an electrically induced vortical flow system, both numerically and experimentally. A 50Hz current is applied between a small bottom elec- trode at the center and a conducting cylindrical side wall, and consequently an upward fluid jet is driven causing a notable free surface deformation. The surface jet height measurements at relatively low currents are in good agreement with the axisymmetric numerical model. Increas- ing injected current leads to melt swirling and free surface sloshing, which cannot be modelled in an axisymmetric approximation. 3D simulations have revealed the melt rotation and surface instabilities.
