Abstract

In a previously developed phase-field model of solidification that includes convection in the melt, the two phases are represented as viscous liquids, where the putative solid phase has a viscosity much larger than the liquid phase. In this paper we report numerical computations on a simplified form of this model which represents the growth of a two-dimensional dendrite in a thin gap between twoparallel thermally insulting plates. In these computations flow in the liquid arises because of the differing densities of the solid and liquid phases.
