Abstract Scope A three-dimensional numerical model of fluid flow, temperature, and solidification is developed to analyze the effect of a ruler electromagnetic brake (EMBr) over a single-phase flow of steel in a CSP mold using the enthalpy porosity method and the k-ε Realizable to account for the turbulent nature of the flow inside the mold. The model is partially validated by comparing the results of fluid flow, thermal behavior, and shell growth thickness against those reported in the literature. Then, a magnetohydrodynamic model (MHD) was coupled to consider the effect of the EMBr over the molten steel. The results show that the EMBr reduces the velocity of the molten steel at the mold exit by ~55%. The EMBr also slightly increases the meniscus temperature from 1,803 K to 1,807 K, while producing only a minor reduction in the solidified shell thickness (from 9.3334 mm to 9.2443 mm at mold exit).
