Fluid Physics Track – Research Groups
The three research groups that are involved in the Fluid Physics track are:
The Physics of Fluids (PoF) group works on a variety of aspects in fluid mechanics, in particular on those related to bubbles. The focus of our work is the fundamental understanding the phenomena of the physics of fluids, bubbles and jets, which we undertake by experimental, numerical and theoretical means. The main research areas are Turbulence and Two-phase Flow, Granular Flow, Micro- and Nanofluidics and Biomedical Applications of Bubbles. The group has two unique experimental facilities: the 9-m vertical water channel to study turbulent bubbly flows and the Brandaris digital ultra high-speed imaging facility. Physics of Fluids has many national and international contacts, both in industry and in the academic world.
A liquid itself is essentially characterized by two parameters: density and viscosity. In the Physics of Complex Fluids (PCF) group, we are interested in situations that require a more detailed description of the liquid itself. Such situations arise for instance when liquids are confined to narrow pores: at some point the properties of the individual molecules begin to show and the liquid ceases to behave as a continuum. Another example is the fluids within our bodies. They are complex by virtue of their composites, ranging from water molecules to proteins, to organelles, to entire cells. Again, a description of these liquids requires a much closer look (and many more parameters) than simple liquids. In the PCF group, we use various optical microscopy techniques (including confocal laser scanning and high speed video microscopy) as well as mechanical probes such as Atomic Force Microscopy and the Surface Forces Apparatus to characterize the behavior of complex fluids from the nano- to micrometer scale.
The research in the group Computational Biophysics (CBP) focuses on the relation between the
constitution of various matters and their rheological properties. Studies are performed
using simulation methods ranging from molecular dynamics simulation,
