Akustische Beeinflussung einer Instabilität in Kanälen mit überströmten Resonatoren

Jüschke, Matthias (2006-09-01)

The sound-flow interaction in an acoustically lined section of an otherwise rigid duct is investigated. Turbulent fluctuations or imposed oscillations of the flow at the inlet of the lined ...

Experimental study of lipid membranes: lipid domain formation and peptide aggregation.

Oliynyk, Vitaliy (2006-06-22)

In the presented work we have attemptted to improve our understanding of the factors which lead to the formation of lipid membrane spatial heterogeneities, caused by mixtures of different lipids and/or transmembrane peptides. ...

Unsteady gas flows and particle dynamics in the shock layer formed by the impingement of a supersonic two-phase jet onto a plate

Klinkov, Konstantin (2005-08-10)

Supersonic particle-laden jets impinging normally on plates are studied. The free jet studied is characterized by Mach numbers of 2.6-2.8 and stagnation temperatures of 300-500 K. The ...

Modenstruktur und adaptive Regelung der Strahl-Kanten-Strömung

Ickler, Arno (2005-02-14)

The stabilization of the plane laminar jet-edge-flow is studied with the general objective to gain some gerneral experience with flow control. The convective instability of the jet combined ...

Anregbarkeit der Kelvin-Helmholz-Instabilität in der freien Scherströmung hinter einer scharfen Kante

Tokuno, Hironori (2004-11-29)

The generation and compensation of instability waves in the detached free shear layer behind the trailing edge of a splitterplate that separated to regions with different flow velocities, ...

Modellbildung für die Schallverstärkung in nachgiebig ausgekleideten Strömungskanälen

Großer, Jakob (2004-01-05)

Short acoustically lined sections of flow ducts can amplify sound that travels downstream at frequencies slightly above the resonance frequency of the lining.I discuss models of this effect ...

Breitbandige Ultraschallabsorptionsspektroskopie an wässrigen ionischen Tensid-Lösungen im Frequenzbereich von 100kHz bis 2GHz

Polacek, Rüdiger (2003-08-12)

Liquids play an important role in animated nature, especially in physical chemistry and biology. On molecular level the macroscopic physical characteristics are to be understood about liquids ...
