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.  mehr...

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.mehr...

Die Abteilung "Fire Protection" bei Airbus in Bremen ist verantwortlich für die Entwicklung der aktiven „Fire Protection Systeme“ in allen kommerziellen Flugzeug-Programmen. Da es sich bei einem unentdeckten Brand im Frachtraum um ein katastrophales Ereignis handelt, sind die Sicherheits- und Zuverlässigkeitsanforderungen hoch. So muss jedes erdenkliche Feuer im Laderaum eines Flugzeuges binnen 60 Sekunden detektiert werden und im Cockpit einen Alarm auslösen. Nach Erhalt eines Rauchalarms im Cockpit erfolgt die schnellstmögliche Landung, d.h. eine Umleitung zum nächstgelegenen Flughafen und der Evakuierung der Passagiere. Da die Frachträume im Unterdeck von der Kabine aus nicht zuganglich sind, sind diese Bereiche zudem mit einer aktiven Brandbekämpfung ausgestattet, die den Brand bis zur sicheren Landung unterdrucktmehr...

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. mehr...

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.  mehr...

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.  mehr...
