Abstract
A numerical investigation was performed using Prandtl mixing-length theory along with the average heat capacity method to model a turbulent plane submerged entry nozzle continuous casting process. This method features the simplicity of a zero-equation model along with ease of maintaining the time-step increment. Results from the study match well with other published data. The current study indicates that submergence depth of the entry nozzle affects the turbulence level and hence controls the quality of the finished product. The inlet speed of the molten metal also controls the solidification front slope and the surface heat flux of the caster.
