Abstract
Direct numerical simulations of 3D dendritic growth in the presence of moderate/high magnetic fields have shown that a significant fluid flow can be driven in the mushy inter-dendritic region. The onset of secondary branching caused by the heat and mass transport of fluid flow causes thermoelectric microcirculations to form, which act to amplify the Lorentz force allowing significant velocities to persist within the inter-dendritic regions. A simplified 1D analytic solution demonstrates that for supercooled dendritic growth the fluid velocity could be comparable to the tip velocity.
