The present work aims at modeling macrosegregation of castings, accounting for the transport of equiaxed grains. A two-phase (solid and liquid) finite element solidification model is presented, consisting in solving a system of volume-averaged conservation equations of energy, momentum, solute, in which the multi-scale evolutions of phase and solute mass are modeled by using a splitting method. According to this approach, the variation of quantities is considered as due to the contribution of two stages: the growth stage and the transport stage. The numerical implementation was realized with three principal steps: first implementing growth processes, then integrating transport phenomena including the thermo-solutal liquid convection and the...
