Numerical Simulation of Optimizing SEN Structure for Wide Slab Caster Mold

The fluid flow in a wide slab continuous caster mold was simulated by a three-dimensional model set up using the commercial software PHOENICS.The effects of the nozzle bottom construction,outlet angle and immersion depth of SEN (submerged entry nozzle) on the wave amplitude of the fluid near the interface was tested,and the influence of fluid flow on the impetus to narrow side of mold and the level of vortex center was also tested.So the reasonable SEN structure was put forward for the wide slab caster mold,this could be an available basis for optimum fluid flow and SEN design of a wide slab continuous caster mold.
