Abstract
Direct numerical simulations of 3D dendritic growth in the presence of moderate-high magnetic fields have shown that significant fluid flow can be driven in the mushy interdendritic region. The onset of secondary branches caused by the heat and mass transport of fluid flow causes thermoelectric microcirculations to form, which act to amplify the Lorentz force. However magnetic damping will dominate when a region lacks thermoelectric currents.
