A fixed grid numerical modelling methodology for convection-diffusion mushy region phase-change problems
Vaughan R Voller,C. Prakash +1 more
TL;DR: In this article, an enthalpy formulation based fixed grid methodology is developed for the numerical solution of convection-diffusion controlled mushy region phase-change problems, where the basic feature of the proposed method lies in the representation of the latent heat of evolution, and of the flow in the solid-liquid mushy zone, by suitably chosen sources.

A continuum model for momentum, heat and species transport in binary solid-liquid phase change systems—I. Model formulation
W.D. Bennon,Frank P. Incropera +1 more
TL;DR: In this article, a set of continuum conservation equations for binary, solid-liquid phase change systems is presented. But these equations have been cast into forms amenable to clear physical interpretation and solution by conventional numerical procedures.

Formation of macrosegregation by multicomponent thermosolutal convection during the solidification of steel
TL;DR: In this article, the formation of macrosegregation by multicomponent thermosolutal convection during the solidification of steel is simulated by simultaneously solving macroscopic mass, momentum, energy, and species conservation equations with full coupling of the temperature and concentrations through thermodynamic equilibrium at the solid/liquid interface.
