Macrosegregation presents a considerable defect in the continuous casting of billets and can critically affect the final properties of the product. The numerical modelling can help to predict and better understand the segregation and flow patterns inside the mould. The process is modelled with a physical model described by a set of conservation equations describing the heat transfer, turbulence, fluid flow, solidification and segregation. A two-equation low-Re k-epsilon model and Abe-Kondoh-Nagano closures are used to close governing equations in this incompressible fluid flow example. The results indicate that the proposed modelling approach can effectively predict the flow behavior and segregation patterns, resulting in improved understanding of the continuous casting process and potential corrective measures. This work contributes to the development of strategies aimed at minimizing macrosegregation and enhancing the quality of steel products during production.
