The Max Planck-University of Twente Center for Complex Fluid Dynamics is an interdisciplinary platform shared between the MPI for Dynamics and Self-Organization in Göttingen, the MPI for Polymer Research in Mainz, and the University of Twente in Enschede, The Netherlands. Together, we aim to understand the complexities inherent to multi-component fluids on all length scales, from nanoscopic surface interactions to large-scale turbulent flows. The Groups of Stefan Karpitschka and Corinna Maass are participating in the Center, both in the context of Marangoni-driven flows. These flows are popularly known from the “Tears of Wine” effect, and early research dates back even to the 19th century where Carlo Marangoni and James Clerk Maxwell were working on it. Even today we do not understand many aspects of this effect, primarily due to the complex nature of the liquids that show it. Recent technological advances, e.g. in ink-jet printing, are demanding a better knowledge, and, at the same time, bring advancements into tangible reach.
