A 2D transient axisymmetric model has been established to investigate the effects of solidification path and permeability model on ingot solidification in electroslag remelting process based on the volume of fluid (VOF) and dynamic mesh technique. The governing equations are discretized by means of the finite volume method (FVM). The modified heat capacity is employed including the change in enthalpy. The hypothetic linear dependence and the solidification path obtained from Thermal-Calc are incorporated into the model with User Defined Function (UDF) respectively. The Dracy’s law is used to describe the flow in the mushy zone. Both the isotropy permeability and anisotropy permeability model are employed for comparison. The local solidification time (LST) is also predicted. The results could enhance the understanding of ingot solidification.
