Hurricanes are effected by turbulent natural convection flows, which are caused by solar radiation. To understand the hydrodynamic stability of these flows, especially in terms of the Coriolis acceleration of the earth rotation, the first step is an investigation of a simplified convection problem. more...

It is proposed to establish a Collaborative Research Centre (SFB) with the title “Autonomous Lunar Infrastructures (ALI)” at University of Bremen with several cooperating partners close by. Bremen is an important site in Germany where space related activities are concentrated with more than 1500 engineers and scientists working in the fields of development, production, operation and utilisation of orbital and exploration systems, satellites and launchers. more...mehr...

Thermally driven flows are described as a turbulent compressible Rayleigh-B´enard problem. For the numerical discretisation of the Large-Eddy-Simulation the flow is separated in large and small scales, the so-called sub-grid scales. more...

This set-up forces a debris flow at the groung of the cylinder. Additionally the interface between debris and liquid media is destabilized. The new steady shifting form depends on debris material and the mean shear stress at the surface of the granular bed. more...

The subject of interest is the validation of a 3-D numerical computer model of a hypersonic flow around double cone geometry. The double cone geometry represent a generic space vehicle which enters an atmosphere with very high velocity. more...

The objective of this study is to prove the feasibility of the suggested technical concept and validate the elementary performance calculations. Besides gas- and thermodynamic analyses, this includes basic examinations on some options for the supporting structure; more...mehr...
