Location
The core facility center is located in the Fluid-Center-building,
on the campus of the Brandenburg University of Technology,
Siemens-Halske-Ring 14, 03046 Cottbus, Germany.
The Department of Aerodynamics and Fluid Mechanics is
responsible for the experiments. In total 26 technical & scien-
tific employees are working here on experimental, theoretical
and numerical questions of fluid mechanics.

Service offered by the core facility center
Generally we offer two types of services:
i) in situ research with a direct access to the facility
ii) commissioned research
In the first case i), the user in person will be conducting
the research at our facility. To these researchers we
offer practical guidance as well as technical assistance
on the part of our scientific and/or technical staff, which
is necessary due to the high complexity of the
experimental installations. In preparation of such joint
research project, the user will work with the facility lead
scientist and the facility technician. The guesthouse of
the BTU will minimize the organizational effort required
for arranging the visits to the different facilities.
In the second case ii), the commissioned research, the
user can demand for certain measurements to be
performed at our facility without being actually present in
Cottbus. In this case our personnel will carry out the
requested measurements and transmit the results to the
user. This type of research is particularly appealing to
users from the computational fluid dynamics community
who are interested in validating their numerical data
using experimental data.
The DFG core facility center “Physics of Rotating Fluids”
• Planetary and astrophysical flows (with focus on
disk formation, instabilities and mixing)
• Geophysical fluid dynamics (with focus on strato-
rotational turbulence, mean flow generation and
wave interaction)
• Rotating flows with technical applications
(centrifuges, turbines, journal bearings and
rotor/stator cavities)
The new core facility center “Physics of Rotating Fluids”
covers and focus all previous single research and guest
scientist exchange activities in the field of stratified and
rotating fluids:

Geoflow-Experiments
The new DFG core facility center “Physics of Rotating Fluids”
establishes a new international research center in form
of a core facility center with geo-/astrophysical, mete-
orological and technical applications located at BTU.
The main goal is to integrate cutting-edge rotating and
stratified fluid flow experiments across national boun-
daries in order to foster internationally competitive
experimental research in the research field of rotating
and stratified fluids by providing an easy access to
outstanding experimental facilities equipped with state-
of-the-art instrumentation. The research areas covered
by the experimental facilities inside the new center are:
