Physics of Complex Fluids Group

The research goal of PCF is to understand and to control liquids and their interfaces from molecular to macroscopic scales. Our research connects fundamental phenomena in static and dynamic wetting, nanofluidics, microfluidic two-phase flow, functional surfaces, drop impact, and drop evaporation to practically relevant applications such as enhanced oil recovery, lab-on-a-chip systems, analytical chemistry (MALDI-MS), optofluidics, and inkjet printing.

New (Chemical) Industrial Partnership Program (CH)IPP started

FOM, NWO/CW and BP started a new program on fundamental physical and chemical aspects of enhanced oil recovery under the coordination of Frieder Mugele. Building on an earlier bilateral collaboration between the PCF group and BP, ... read more

Stability limits of capillary bridges: new publication in Physical Review Letters

The morphology of liquid drops on the micrometer scale is governed by the geometry and the wettability of surrounding surfaces. These boundary conditions can lead to rather complex energy landscapes, frequently with multiple local minima corresponding to competing liquid morphologies. In collaboration with Ciro Semprebon and Martin Brinkmann from the Max-Planck-Institute for Dynamics and Self Organization, ... read more

CFD model in OpenFOAM for electrowetting-driven two phase flow microfluidics

Ivo Roghair, formerly at PCF and now at Tu/e, and co-workers published a CFD model to described the dynamics of the motion of drops in the presence of electric fields in the journal Microfluidics Nanofluidics. ... read more

Jolet de Ruiter obtained a Rubicon grant from NWO

Congratulations, Jolet!
Former PCF PhD student Jolet de Ruiter obtained a Rubicon grant from NWO to continue her work as a Postdoc in the group of Prof. Kripa Varanasi at MIT in Boston. Jolet’s proposal entitled “Study of drop impact and freezing dynamics under icing conditions” was one of four successful Rubicon proposals in January 2015. Good luck with your work, Jolet! ... read more
