Coherent structures in turbulent Rayleigh-Bénard convection
(2006-01-17)Coherent structures on different length scales are investigated in turbulent Rayleigh-Bénard convection. In thermal boundary layers a previously unknown type of coherent structures is ... -
Fluid instabilities in precessing ellipsoidal shells
(2002-02-06)The Earth precesses with a period of 25700 years due to the gravity fields of the Moon and the Sun acting on the Earth's equatorial bulge. The influence of the Earth's precessional motion ... -
Partikelmodellierung der Strukturbildung akustischer Kavitationsblasen in Wechselwirkung mit dem Schalldruckfeld
(2006-10-10)When a strong acoustic field is coupled into a liquid, it ruptures and bubbles emerge (acoustic cavitation). The acoustic cavitation bubbles show volume oscillations as well as a translative ... -
Unsteady gas flows and particle dynamics in the shock layer formed by the impingement of a supersonic two-phase jet onto a plate
(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 ... -
Untersuchungen zur laserinduzierten Kavitation mit Nanosekunden- und Femtosekundenlasern
(2004-02-27)The optical breakdown in the focus of a strong laser pulse can rupture liquids. A bubble is formed, which can serve as a well reproducible model for the investigation of cavitation mechanisms.In ...
