Collaborative Research Center 1194
Interaction between Transport and Wetting Processes
1st funding period (July 1, 2016 – June 30, 2020)
The Collaborative Research Center (CRC) 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 – particularly when, parallel to momentum transport, also heat and mass transport, complex fluids or complex surfaces are involved.
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.
To date research in this area has focused on the dependence of the wetting process on the local fluid velocity at the contact line, i.e. wetting coupled with momentum transport. However serious deficits exist in our understanding when, parallel to momentum transport, also heat and mass transport are involved. These deficits become even more blatant when complex fluids are involved, e.g. suspensions or mixtures, or when complex surfaces are examined, e.g. rough or porous.
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 CRC is grouped into three research areas:
Upcoming Lectures & Events
Nanofluids for Boiling Heat Transfer Applications: from a Hopeless Task to New Research Opportunities
Talk by Simone Mancin, University of Padova
Nanoparticle deposition during boiling has opened new research opportunities introducing a new concept of surface functionalization using a low-cost, easy-to-implement deposition technique. Simone Mancin (University of Padova) will present latest research activities. go
Talk by Gary Rosengarten (RMIT University)
Typical heat transfer correlations or surface property data assume that surfaces are smooth, or that they don’t effect transport properties such as convection or even radiation. However, nano-scaled features can have a massive effect on many transport properties- particularly those with free surfaces. go
