| Abstract Scope |
A Navier-Stokes-Cahn-Hilliard (NSCH) model is presented to describe the initial solidification phenomena within a continuous casting mold. This model addresses heat transfer, fluid flow, and solidification, coupled with mold oscillation and including the slag phase. The model is based on the principle that a thermodynamic system evolves towards a state of minimal free energy. To ensure convergence of the NSCH equations to those of the sharp-interface model, the interface width, mobility, and mesh size were carefully chosen within the capabilities of current computational resources. It is highly recommended to employ adaptive mesh refinement to achieve efficient numerical computation of phase-field models. Comparison of the initial meniscus shell shapes predicted by the NSCH model with actual observations demonstrates that the NSCH model can accurately reproduces the initial solidification phenomena occurring within the oscillating continuous casting mold. |
