Industrial production of emulsions comprises a rich set of multiphase phenomena, not only during the initial emulsification, but also after production, e.g. during pumping, filtering, and filling. In a flowing concentrated emulsion, droplets can deform, aggregate, break up, coalesce, stick to/release from walls, or migrate and self-organize within the flow field. The dynamics of these phenomena become even richer when considering the spreading of surfactants/polymers to facilitate the flow as for example done in enhanced oil recovery. Understanding these different phenomena is crucial for predicting the performance and stability of emulsion-based products. This project does not stand on its own, but is part of a larger synergetic research program between different academic and industrial partners.
Project goal and description:
The goal of this project is to advance the current understanding on how concentrated emulsions flow through narrow constrictions. More specifically, we aim to understand how complex flow patterns are governed by the rich interplay between the cooperative motion of the droplets, the microstructure of the emulsion and the geometry of constrictions. To this end, we will develop and use experimental techniques, such as micro Particle Image Velocimery, to study such flows in model geometries made in microfluidic devices.
We are looking for a postdoc with interest in the areas of microscale fluid dynamics, emulsions, and soft matter physics. You should have:
- a PhD degree in applied physics, chemical engineering, food technology, mechanical engineering or a similar discipline, with excellent laboratory skills (preferably microscopy and microfluidics).
- a strong theoretical background in fluid dynamics and transport phenomena, preferably complemented with a good understanding of surface tension phenomena and soft matter physics.
- a curious mind-set, self-driven, not afraid to take initiative, and able to easily communicate with others.
- a high English proficiency in speaking, writing and reading.
