Vapor compression and energy dissipation in a collapsing laser-induced bubble
Mohamed Farhat, Danail Obreschkow, Davide Bernardo Preso, Armand Baptiste Sieber
The composition of the gaseous phase of cavitation bubbles and its role on the collapse remains to date poorly understood. In this work, experiments of single cavitation bubbles in aqueous ammonia serve as a novel approach to investigate the effect of the ...
Melville2024The influence of the gas on the dynamics of cavitation bubbles
Cavitation bubbles, extensively investigated in fluid mechanics, present enduring challenges in hydraulic machinery, while holding considerable potential for practical applications in biomedicine and sonochemistry. Despite more than a century of research, ...
EPFL2023Ex uno plures: how to construct high-speed movies of collapsing cavitation bubbles from a single image
Mohamed Farhat, Davide Bernardo Preso, Armand Baptiste Sieber
The time-resolved visualization of the dynamics of a cavitation bubble usually requires the use of expensive high-speed cameras, which often provide a limited spatial resolution. In the present study, we propose an alternative to these high-speed imaging t ...
New York2023Interactions of Cavitation Bubbles with Deformable Interfaces
Cavitation is a topic that has long been of interest due to the large and growing range of applications associated with it. This is mainly because the collapse of cavitation bubbles releases a considerable amount of energy into the surrounding environment. ...
EPFL2023Dynamics of cavitation bubbles near granular boundaries
Mohamed Farhat, Davide Bernardo Preso, Armand Baptiste Sieber
We study the dynamics of a cavitation bubble near beds of sand of different grain sizes. We use high-speed imaging to observe the motion of the bubble and the sand for different values of the stand-off parameter gamma (dimensionless bubble-boundary distanc ...
CAMBRIDGE UNIV PRESS2022Bubble-enhanced ultrasonic microfluidic chip for rapid DNA fragmentation
Martinus Gijs, Thomas Lehnert, Lin Sun
DNA fragmentation is an essential process in developing genetic sequencing strategies, genetic research, as well as for the diagnosis of diseases with a genetic signature like cancer. Efficient on-chip DNA fragmentation protocols would be beneficial to pro ...
