Numerical Modeling

A model is prepared to best represent the cast of the continuously casting process, which is simple enough to numerically evaluate the effect of EMS on the process.
The following assumptions are made in this work:
The governing theories for flow of the fluid, its phase interaction and ensuing solidification after its filling of the mold for this problem are discussed below.

Multiphase modeling

The liquid steel is treated as an interpenetrating continua where the volume of primary phase (air) is not penetrated by secondary phase (steel). The tracking of each phase is calculated using volume fraction (\(\alpha\)) which is evaluated explicitly with the following expression:
