The significance of coherent flow structures for the turbulent mixing in wall-bounded flows
(2004-07-28)For the identification and characterisation of coherent flow structures in turbulent boundary layers and for the examination of the interaction processes between these structures, a flat ... -
Investigation of transition scenarios in boundary-layer flows
(2002-04-05)Laminar-turbulent transition mechanisms triggered by crossflow instability in three-dimensional, accelerated boundary-layer flows are investigated us- ing numerical methods of stability analysis. The investigations are ... -
Untersuchung der Strukturen von künstlich angeregten transitionellen Plattengrenzschichtströmungen mit Hilfe der Stereo und Multiplane Particle Image Velocimetry
(2001-12-05)Stereoscopic and Multi-plane PIV measurements on artificially excited transitional boundary layer flows along a flat plate will be presented. The experimental results are focused on the ... -
Entwurfsaerodynamische Studien an Tragflügelkonfigurationen im Hochgeschwindigkeitsbereich mit evolutionären Algorithmen
(2001-11-06)Not available. -
Experimentelle Untersuchungen des laminar-turbulenten Überganges der Zylindergrenzschichtströmung
(2001-07-18)The spatio-temporal separation of transitional boundary-layer of the cross-stream cylinder-flow is explored in the subcritical up to the transcritical Reynolds number regime. In order to ... -
Mehrkomponenten-Laser-Doppler-Anemometer-Messungen in einer drallbehafteten Rohr- und Brennkammerströmung
(2001-06-06)Swirl flows, i.e. axisymmetric jet flows with a non zero circumferential velocity, are important in technology as well as in nature. Swirl flows occur in a wide range of applications like ... -
Investigation of transition scenarios in boundary-layer flows
(1999)Laminar-turbulent transition mechanisms triggered by crossflow instability in three-dimensional, accelerated boundary-layer flows are investigated using numerical methods of stability anaylsis. The investigations are based ...
