Abstract

A fully coupled 3-dimensional numerical model is used to analyse the effect of magnetic field orientation on dendritic growth. For materials that exhibit a significant thermoelectric power, the results show significant differences in the dendritic morphology for different orientations of the field. These variations can be attributed to fluid flow generated through Thermoelectric Magnetohydrodynamics. A simplified, steady-state, low-field solution during the early stages of growth is used to describe how the fluid flow alters with the orientation of the field and how these flow features can lead to the final morphologies for well developed dendrites.
