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:
