Recent experimental observations showed strong effects of static magnetic fields on free dendritic growth from undercooled melts . Those effects were attributed to competition of two kinds of flow patterns driven by thermoelectric magnetohydyodynamic (TEMHD) convection . To have insight into those effects, we modeled flow velocities of a transverse TEMHD flow pattern for two metals, Fe and Ni. Then, we modeled tip growth velocities of the two metals under the influence of such flow velocities using a theory of three-dimensional dendritic growth . The calculated tip velocities show a reasonable agreement with the experimental observations . The authors are grateful to financial support by the NSFC and the Royal Society of UK.
