Nowadays, the Vacuum Arc Remelting (VAR) process is effectively utilized to manufacture Titanium-based alloys. A comprehensive CFD model is proposed to study the interaction between various transport phenomena (flow, heat, etc.) in the VAR. All elements of the process including the electrode, vacuum, Titanium-based ingot, and mold are taken into account. The electromagnetic field is calculated in the entire process. The flow filed in the melt pool is computed. Furthermore, the pool profile of the solidified ingot is calculated. The model enables us to compute the radiation heat transfer in the vacuum region where the amount of side-arcing is prescribed. The impact of side-arcing on the magnetohydrodynamics behaviour of the melt pool and consequently the pool profile of the ingot is analysed. Eventually, the model is validated against an experiment.
