Discretization of Mass Forces and its Impact on Drop Break-up in Stirrers.

Kurzbeschreibung (Abstract)
The presence of two-phase flow and complex geometry is the main difficulty during the computation of a flow field in a stirrer. The interface capturing Volume of Fluid method, implemented in the framework of a finite volume Navier-Stokes solver, is used to determine the bubble break-up location and the bubble diameter distribution after the collision with the stirrer plate. Comparisons of numerical and experimental results are given. Moreover, the impact of different discretization schemes of mass forces on non-orthogonal grids (e.g. gravity or surface tension) on simulation results are studied.
