CRC 1194 - Interaction between Transport and Wetting Processes

Collaborative Research Center 1194

Interaction between Transport and Wetting Processes

1st funding period (July 1, 2016 – June 30, 2020)

The Collaborative Research Center 1194 involves researchers from the TU Darmstadt and the Max Planck Institute for Polymer Research Mainz. Their common goal is the fundamental analysis of the interaction between transport and wetting processes.

What happens when surfaces are printed and coated with different liquids? What processes occur when a liquid meets a solid? How do wetting and dewetting depend on the local momentum, heat and mass transport processes? The underlying mechanisms of the interaction between these processes have to a large extent not been understood to date and are the focus of the Collaborative Research Centre (CRC) 1194. Although the physical phenomena take place only in a range of nanometres or micrometres, they often determine the efficiency of the overall process and the resulting product quality.

The CRC focuses particularly on the interactions between wetting and transport processes when, parallel to momentum transport, also heat and mass transport or when complex fluids are involved, or when complex surfaces are examined.

Fundamental processes and phenomena are examined over a wide range of length scales (nano-micro-macro) and the transfer of basic research to applications is an integral part of the research program. Overall the subject demands the use of very diverse methods and expertise from a multitude of disciplines.

The SFB comprises 18 subprojects grouped into three research areas:

(A) Generic Experiments

(B) Modelling and Simulation

(C) New and Improved Applications.

As an overarching and integrating factor two generic configurations have been specified (Immersed Body, Sessile Drop). Furthermore, OpenFOAM has been selected as a common software platform.
