Abstract

A model of binary alloy solidification is formulated using the mass, momentum and en- ergy balances in the liquid and the mass and energy balances in the solid. The interface between the solid and liquid phases is modeled as a discontinuity surface where the mass, momentum and energy balance conditions are expressed. The numerical solution of the mathematical model is performed using the Galerkin finite element method in a 2-D approximation with the cylindrical symmetry and the moving boundary problem is solved by a front-fixing tech
