The presence of turbulence in the human aorta has been historically linked with cardiovascular diseases. It is thus of the interest to understand how aortic flows can transition to turbulence and how turbulence behaves once it is triggered. more...
Cardiovascular flows are pulsatile in nature and characterized by complex geometries, fluid
structure interaction and non-Newtonian behavior.
Quantum physics is becoming more and more attention from science and economy. Often alkali-metals evaporated in an ultra-high vacuum are used as source for quantum technologies. Recently we developed a filling facility for alkali-metal sources such as ovens or dispenser in our laboratories. The next step is to qualify existing ovens with a saturation spectroscopy unit for space based missions.more...

The "Fire Protection" department at Airbus in Bremen is responsible for the development of active fire protection systems in all commercial aircraft programs. As an undetected fire in the cargo compartment is a catastrophic event, the safety and reliability requirements are high. For example, any conceivable fire in the cargo compartment of an aircraft must be detected within 60 seconds and trigger an alarm in the cockpit. After receiving a smoke alarm in the cockpit, the fastest possible landing is made, i.e., a detour to the nearest airport and the evacuation of passengers. As the cargo compartments on the lower deck are not accessible from the cabin, these areas are also equipped with an active fire suppression system that will suppress the fire until the aircraft can land safely.
The precise non-gravitational force modeling is a perquisite for many tasks related to orbit determination and propagation, mission assessment and performance analysis. Especially for scientific missions (altimetry, geodesy, general physics, as well as GNSS) highly accurate models are very important. more...

The density of the thermosphere is of high relevance for the propagation and determination of satellite trajectories in Low Earth Orbit (LEO). The drag acceleration, results in a change of trajectory and an orbital decay. This has implications for active satellites, where a precise orbit or position knowledge might be crucial for the mission success (e.g. altimetry, gravimetry, remote sensing), for maneuver planning and satellite lifetime prediction, as well as for space debris, where position determination is important for collision avoidance and reentry calculations. more...
Dynamic POD is used to determine orbits or positions of satellites based on various observation data. Furthermore, it is possible and widespread to determine additionally parameters of force models of all kinds. Observation data might be data with respect to other satellites like GNSS data or inter-satellite ranging, as well as measurements from ground like ranges or angles. A prominent technique is Satellite Laser Ranging (SLR), giving ranges between a SLR station and a satellite at distinct times. more...
