The present work models the fluid flow and heat transfer with solidification of a steel in the funnel type mold region of a thin slab steel continuous caster. In current modeling a turbulent fluid flow has been supposed and used K- e model in order to anticipate the heat transfer distribution in mold region. To consider the solidification effects on fluid flow and solid crust, the Darci model was applied, also for outlet heat flow measurement a simple method was used. The fluid flowresults indicate a special flow pattern in the caste for a tetra-furcated nozzle. revealed to have two large downward and upward recirculation zones with a classic double-roll and two small vortices generated by the upward flow from the upper ports of the submerged entry nozzle. Heat transfer results indicate that increasing the continuous casting velocity and reducing submergence depth would lead to reduction in the thichness of the solidified shell while decrease the surface freezingFinally achieved the optimum condition related to heat transfer phenomena and surface distribution .
