We are offering a PhD student position in the Multiphase Flow group at the
Division of Fluid Dynamics, in a project carried out in collaboration with
Fraunhofer-Chalmers Centre. We are going to investigate migration, mixing and
modulation in reactive Brownian systems of arbitrary geometric complexity
using our own state-of-the-art multiphase direct numerical simulation (DNS)
method. These investigations are crucial to enable optimization of
applications governed by the motion of metal nanoparticles, colloid
contaminants, macromolecules, cellular bacteria, red blood cells, DNA, and
fractal aggregates. Such applications include, for example, micro- or
nanofluidic reactors, lab-on-a-chip devices and surface-based sensors.
We are looking for a creative new colleague that wants to take on this
challenge together with us. The group has approximately 15 members of varying
backgrounds and research interests.
Transport of reactive Brownian particles of complex shape in intricate
geometries plays a key role in a wide range of industrial and biological
systems. In some applications, such as sensors, the ambition is to get a
target particle as quickly as possible to a surface. In others, such as
microfluidic reactors, particle-wall interactions lead to fouling,
deterioration of functionality and eventually blockage of the flow system.
In these processes, particles move in meandering trajectories due to thermal
fluctuations while being transported with the flow. The interaction between
particles of different kinds, and between particles and walls, can be very
complex. Variations in particle shapes, sizes, and concentrations, as well as
the details of the bounding geometry and the characteristics of the carrier
flow, tend to give rise to particle migration.
In this project, we will use our previously developed computational framework
to study migration, mixing and modulation in geometrically complex reactive
Brownian systems. We will identify under what conditions one can enhance or
suppress the transport of a Brownian particle towards a surface. The results
will be crucial for the further development and optimization of surface-based
sensing techniques, for high-level control of mixing and segregation phenomena
in microfluidic devices, and for anti-fouling measures in microfluidic
Your major responsibilities as a PhD student is to pursue your own doctoral
studies. You are expected to develop your own scientific concepts and
communicate the results of your research verbally and in writing. Your
research will be supervised by several well-reputed senior researchers,
offering a supportive environment for performing cutting-edge research.
The position also includes teaching or other departmental duties corresponding
to 10-20 % of working hours.
Full-time temporary employment. The position is limited to a maximum of
4.5-5 years depending on the amount of teaching and departmental work during
your doctoral project.
To qualify as a PhD student, you must have a master's level degree
corresponding to at least 240 higher education credits in a relevant field
(such as Mechanical Engineering, Chemical Engineering, Engineering Physics,
Engineering Mathematics or similar). The position requires sound verbal and
written communication skills in Swedish and English. If Swedish is not your
native language, you should be able to teach in Swedish after two years.
Chalmers offers Swedish courses.
We think that you are a self-propelled and motivated person that tend to plan
and think strategically. You are creative and like to put new ideas into
practice. You have a solid interest in scientific computing and a strong
natural curiosity with a genuine wish to learn more and develop your skills
and knowledge further in the fields of research, research communication and
project management. Previous programming experiences are considered
