Mathematical modelling of solidification of a binary alloy

Abstrakt/Abstract:
We study the two-dimensional solidification of a binary alloy by numerical means. We employ a front-fixing transformation and develop a finite-difference scheme to simulate the evolution of an initially-planar solidification front. The self-similar solution is taken as a seed field in cases when the melt is constitutionally supercooled. In the regime considered, we find that the solid--liquid interface takes the form of a travelling wave. The parametric dependence of the numerical solution is also investigated.
