Bubble dynamics in liquid metals under external magnetic field

In this study, Computational Fluid Dynamics (CFD) simulation was used to derive full understanding of a bubble rising in liquid metals with and without the presence of an external magnetic field. The major aim of the study was to develop new correlations for bubble velocity and bubble deformation in liquid metals. In house code PSI-BOIL has been used for the simulations. Single bubble rising in quiescent liquid is simulated for three different set of materials (Nitrogen+Mercury, Argon+GalnSn, Argon+Steel). The influence of external horizontal magnetic field on bubble dynamics is analyzed, vertical magnetic field is not considered in this study. On overall, the computed results show that horizontal magnetic field reduces bubble rising velocity, straightens the bubble trajectory and enhances bubble interface stability.
