Abstract: Abstract The rise behavior of small bubbles in a quiescent environment has been investigated by direct numerical simulation (DNS) using the Volume of Fluid (VOF) method and surface tension modeling based on the balanced force approach. The origin of spurious currents using standard (CSF, CSS) models is shown in detail, emphasis is put on the spatial discretization and the calculation of local curvatures. The effect of the new surface tension model on the resulting rise behavior for different bubble diameters is presented.
