Front tracking based macroscopic modeling of equiaxed and columnar zones in a binary alloy solidification

Miroslaw Seredynski, Jerzy Banaszek


The Front Tracking based computer simulation model of solid-liquid phase transition driven by diffusion and thermo-solutal natural convection is presented, and its predictions are verified and validated by comparison with the data obtained from the other available numerical solution and the experimental study. The front tracking approach, based on local dendrite tip kinetics, is capable to distinguish zones of a columnar mush and of the equiaxed grains and, thus, provides means for more precise modeling of a binary alloy solidification.
