3D numerical simulation of the VAR consumable electrode melting process
TL;DR: In this article, a 3D numerical model was set up to simulate the formation and dynamics of the liquid metal film under the consumable electrode during VAR process, which was developed using the open source computational fluid dynamics (CFD) software OpenFOAM.

Probabilistic modelling of microstructure formation in solidification processes
TL;DR: In this article, a new approach to the modelling of grain structure formation in solidification processes is proposed based upon a two-dimensional cellular automata technique, the model includes the mechanisms of heterogeneous nucleation and of grain growth.

A coupled finite element-cellular automaton model for the prediction of dendritic grain structures in solidification processes
Ch.-A. Gandin,Michel Rappaz +1 more
TL;DR: In this paper, a 2D cellular automata (CA) technique is proposed for the simulation of dendritic grain formation during solidification, which takes into account the heterogeneous nucleation, the growth kinetics and the preferential growth directions of the dendrites.

Segregation Development in Multiple Melt Vacuum Arc Remelting
TL;DR: In this article, a numerical model of the vacuum arc remelting (VAR) process was used to study multistage VAR processes and the results of the single stage studies for Ti-10-2-3 were confirmed.
