Abstract:	Agitation of fluids in vials is routinely performed in order to test the suitability of a substance for transport. Many kinds of degradation phenomena can result from such agitation. The specific shear stresses and degradation mechanisms are in many cases not thoroughly understood yet. Studying the shear stress situation due to agitation is an essential step towards understanding degradation mechanisms and specific sensitivities. In order to do this, an OpenFOAM based model has been set-up, using the two phase volume-of-fluid approach within OpenFoam's interFoam solver as well as a frame of reference. Two validation cases have been performed. Firstly, the transient behaviour of the volume- averaged shear stresses in an orbitally shaken fluid have been compared to literature results. Secondly, the structure of the surface waves has been compared to experimental results with water. The developed model has been used to conduct a parameter study for vertical shaking conditions. Thus the shear stress distribution at different excitation frequencies and amplitudes has been investigated.
