Visualization of the flow profile inside a thinning filament during capillary breakup of a polymer solution via particle image velocimetry (PIV) and particle tracking velocimetry (PTV)
S. Gier, C. Wagner
We investigated the flow profile of a polymer solution in a thinning capillary bridge. Fluorescent tracer particles with a diameter of 3m were used to visualize the flow. The cy…

Is there a Relationship between the Elongational Viscosity and the First Normal Stress Difference in Polymer Solutions?
A. Zell, S. Gier, S. Rafaï +1
We investigate a variety of different polymer solutions in shear and elongational flow. The shear flow is created in the cone-plate-geometry of a commercial rheometer. We use capil…
