Characterization of Single and Multiphase Hydrodynamics in Continuous Slab Casting Mold in the Presence of Applied Magnetic Field

A numerical investigation has been carried out to characterize both single and multiphase hydrodynamics in a continuous casting mold under the influence of a superimposed magnetic field. Three-dimensional single- and two-phase magnetohydrodynamic flow and turbulence models have been developed for numerical simulation. The computational model results are in agreement with the plant experimental measurements. In a single phase paradigm, with a functional variation in applied magnetic field distributions, the results have been shown for both conducting and non-conducting media. On the other hand, for multiphase flow, based on the actual magnetic field measurement values at the plant, simulations have been carried out at a representative 6 L/min argon flow rate. Overall, the superimposed magnetic field is observed to subdue the flow velocity magnitude and the distribution of turbulence intensity in the continuous casting mold. A similar phenomenon has also been noticed for multiphase flows.
