The viability of the steel industry depends strongly on product quality and improved efficiency. This article presents a numerical investigation of the turbulent flow in a water model, simulating a continuous steel casting mold. Special attention is given to the free-surface oscillations. The governing differential equations are discretized in a curvilinear coordinate system moving with the free surface by the Finite Volume Methodology (FVM). The results indicate that the free-surface wave has a predominant length and frequency and the wave amplitude scales with the flow dynamic head. Wave instability, which may be associated with emulsification, is predicted at a critical casting speed.
