Abstract

The influence of magnetic fields on single gas bubbles rising in electrically conductive liquids is investigated by direct numerical simulation. For the description of moving and deformable gas-liquid interfaces the hybrid particle-level-set method is employed. As low magnetic Reynolds numbers are considered, the induced magnetic field can be neglected and a simplified magnetohydrodynamic approach can be used. In case magnetic fields are applied, distinct differences with respect to the bubble wakes have been found, which in turn lead to significant changes regarding bubble shapes, rising paths and velocities.
