| Abstract Scope |
Vacuum Arc Remelting (VAR) is a crucial final melt step for aerospace alloys used in critical applications. Numerical simulation plays a crucial role in comprehending the melting and solidification behaviors and assisting in process development for quality control in VAR. This study developed a multi-physics computational model using ANSYS Fluent to simulate the VAR of Inconel 718 in both 2D axisymmetric and 3D configurations. The model incorporates key physics such as magnetohydrodynamics, heat transfer, fluid dynamics, melting, and solidification and facilitates custom initial and boundary conditions through User-Defined Functions (UDF) to study both the steady state and transient behaviors in VAR. The model predicts electromagnetic, fluid flow, and temperature fields, capturing the evolution of the melt pool shape under steady and transient arc behaviors. The results explored various options for arc distribution. Comparisons were made against experimentally measured melt pool geometry and microstructures. The implications of the model boundary conditions on model validation are discussed. |
