title = "Modeling of argon gas behavior in continuous casting of steel",
abstract = "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 through complicated-geometry nozzles increases the complexity of the flow dynamics. In this study, these complex multiphase turbulent flow behaviors are simulated in a lab-scale continuous caster using a new hybrid model that involves a Eulerian-Eulerian (EE) model coupled simultaneously with a Discrete Phase Model (DPM). The complex behavior of the argon gas including formation of gas pockets, intermittent shearing off of the gas pockets, volumetric expansion, coalescence and breakup of bubbles, and transport of the bubbles in both the nozzle and mold are all simulated. The model is validated with measurements on a benchmark experiment of liquid-metal argon flow in a laboratory-scale system. This hybrid model is a promising tool to estimate realistic bubble size distributions and multiphase flow in a real caster.",
