Dynamics of oil–water interface at the beginning of the ultrasonic emulsification process
Žan Boček, Martin Petkovšek, Samuel J. Clark, Kamel Fezzaa, Matevž Dular
Izvirni znanstveni članek
Oznake: cavitation;emulsion;high speed video;x ray visualization;
A lot of effort has been dedicated in recent years towards understanding the basics of cavitation induced emulsification, mainly in the form of single cavitation bubbles. Regarding bulk acoustic emulsification, a lot less research has been done. In our here presented work we utilize advanced high-sp ...

Kelvin-Helmholtz instability as one of the key features for fast and efficient emulsification by hydrodynamic cavitation
Žan Boček, Martin Petkovšek, Samuel J. Clark, Kamel Fezzaa, Matevž Dular
Izvirni znanstveni članek
Oznake: emulsion;hydrodynamic cavitation;Kelvin-Helmholtz instability;Venturi microchannels;
The paper investigates the oil–water emulsification process inside a micro-venturi channel. More specifically, the possible influence of Kelvin-Helmholtz instability on the emulsification process. High-speed visualizations were conducted inside a square venturi constriction with throat dimensions of ...

Fast X-ray imaging of cavitating flows
Ilyass Khlifa, Alexandre Vabre, Marko Hočevar, Kamel Fezzaa, Sylvie Fuzier, Olivier Roussette, Olivier Coutier-Delgosha
Izvirni znanstveni članek
Oznake: cavitation;measurements;x rays;
A new method based on ultra-fast X-ray imaging was developed in this work for the investigation of the dynamics and the structures of complex two-phase flows. In this paper, cavitation was created inside a millimetric 2D Venturi-type test section, while seeding particles were injected into the flow. ...
