In continuous casting of steel, argon gas injection is a popular method to reduce nozzle clogging. Multiphase turbulent flow of molten steel with argon gas increases the complexity of the continuous casting process with its complicated geometry. In this study, these complex multiphase turbulent flow behaviors are simulated in a realistic continuous caster through a new hybrid model that involves a Eulerian Eulerian model coupled simultaneously with a Discrete Phase Model. The complex behavior of the argon gas including formation of argon gas pockets, intermittent shearing off the gas pockets, coalescence and breakup of bubbles, and transport of the bubbles in both the nozzle and mold are all simulated. The model is validated with several laboratory-scale measurements. It is then applied in a parametric study to investigate the effect of different casting conditions on the flow pattern and the evolving bubble size distribution.
