Numerical investigations of relaminarization in scramjet flows
The numerical investigations of relaminarization using statistical turbulence models are presented. The goal is to identify suitable models that can be used in the design and development process of a 3D scramjet inlet by means of numerical methods. The computations were performed using a …

Sichtbarmachung und Geschwindigkeitsmessung in Leeseitenwirbeln bei Überschallanströmung
Plans for future space transportation systems will follow new concepts. The two-stage-to-orbit vehicles (TSTO) are estimated to have a high potential concerning future demands. Their first stage is designed as a lifting body. It is a delta wing for hypersonic flight taking the orbital stage to …

Einfluss des Treibergases auf die Strömung in Stoßwellenkanälen
One of the main aspects of space transportation is the aerodynamic of space vehicles. For the investigation of flow problematic and the interrelated transport phenomenas in hypersonic flows, the development of suitable tools is required. Here, development and verification of such tools is …

Einfluss der Wandtemperatur auf die Stoß-Grenzschicht-Wechselwirkung an einer Rampe im Hyperschall
The C4-metabolism in Maize (Zea mays) serves to efficiently concentrate CO2 near the enzyme RuBisCo. Therefore the photorespiration, as we can find in C3-plants, is suppressed. Although numerous investigations deal with the regulation of the C4-photosynthesis, a lot of factors which take part in it …

Einfluss einer Heckklappe auf die Düsenströmung im Hyperschall
This thesis deals with the flow field at a two-dimensional SERN-Nozzle. Main focus lies on the flow around the nozzle flap and the occurring separation of the boundary-layer of the outer flow. The objective is to get a better understanding of the interacting flow fields and to improve the nozzle …
