Mechanical, Maritime and Materials Engineering
The 3ME Faculty trains committed engineering students and PhD candidates 
in groundbreaking scientific research in the fields of mechanical, 
maritime and materials engineering. 3ME is the epitome of a dynamic, 
innovative faculty, with a European scope that contributes demonstrable 
economic and social benefits. 
This project is a cooperation between the Process and Energy Department 
and the Department of Biotechnology of TU Delft. The work will be carried 
out jointly in the groups for Intensified Reaction and Separation Systems 
of Profs. Peter Jansens and Andrzej Stankiewicz and the Bioseparation 
Technology group of Prof. Luuk van der Wielen. 

Job description
The main aim of this project is the development of a rapid measurement 
technique for multicomponent diffusion coefficients. The setup exploits 
the unique features offered by micro-technology. The novel setup will be 
applied to both biological systems as well as classical solvent systems 
and enable high-throughput analysis of novel (bio)chemical systems with 
respect to mass transport characteristics. This project should thus 
provide a basic tool of immediate value in a broad range of process 
applications ranging from protein purification to CO2 capture.

The work will consist of theoretical studies as well as their experimental 
validation. The experimental part will focus on the setup and run of a 
micro-fluidic device for diffusion measurements. A variety of measurement 
techniques will be employed. The existing prototype device is to be 
adapted and rigorously optimized based on model-based studies employing 
computational fluid dynamics (CFD). The resulting novel device should be 
validated for multicomponent diffusion of proteins as well as for novel 
solvents related to CO2 capture. Future applications and extensions of the 
setup should be explored.

We seek a candidate with an excellent PhD in an area of (bio-)chemical 
engineering, fluid mechanics or a related field. Knowledge and experience 
in the fields of micro-technology, computational fluid mechanics, 
modelling/optimization and/or multicomponent mass transfer in (bio)
chemical mixtures would be advantageous. Fluency in English is a
