Characterization and modeling of ultrasound propagation and cavitation in confined flow geometries
(2024-07-08)Acoustic cavitation is a process by which small bubbles are formed in a liquid that is exposed to sound waves such as ultrasound. These bubbles are peculiar because they expand and collapse violently on themselves resulting ... -
Akustische Strömung in Wasser durch Ultraschall im UHF-Bereich
(2021-06-07)The goal of this predominantly experimental work is the understanding and investigation of acoustic streaming, which is generated by the sound field of new type of a very high frequency transducers. The transducers have ... -
Laser cavitation bubbles at objects: Merging numerical and experimental methods
(2020-12-10)The main body of this thesis deals with the existence of the so called fast jet that develops when a single, laser generated cavitation bubble expands and collapses close to a flat, solid boundary at normalised distances ... -
Erzeugung und Untersuchung von schnellen Mikrotropfen für Reinigungsanwendungen
(2015-06-16)For more than a century, there exists a growing scientific interest in drops and the mechanisms involved during their impact onto various surfaces, probably initiated by the photographic recordings by Worthington (1908). ... -
Untersuchung von akustischen Strömungen im kHz- und GHz-Bereich
(2014-07-14)Launching ultrasound into a fluid can lead to a steady streaming due to nonlinearity and damping. These streaming which is caused by a momentum transfer from the soundwave to the liquid is called acoustic streaming. This ... -
Charakterisierung von Kavitationsblasenpopulationen
(2011-06-22)Acoustic cavitation denotes the nucleation and dynamics of bubbles in liquids under insonication. It is found that bubbles in an acoustic cavitation field do not form a homogeneous group, ...
