CFD modeling of liquid steel flow behaviors in an industrial tundish
Fluid flow dynamics in an industrial-scale tundish was simulated using a computational fluid ynamic (CFD)model incorporating the standard k -εturbulence model and the multiphase volume of fluid (VOF)model.A cold-state simulation was carried out using water to replace the liquid steel.Numerical results show water flow characteristics in the Tundish and the corresponding residence time distribution.The effect of the shape of tundish,interior dams on the hydrodynamics of liquid steel flow were studied numerically to reduce the fraction of dead volume zones and augment nonmetallic inclusions to float into the slag.Such numerical results improve our understanding of the hydrodynamics of liquid steel flow in tundish and contribute to an optimized operation.
