Vortex siphon - from 1:1 scale physical model to SPH simulation and prototype

Giovanni De Cesare

The rail link between Geneva Cornavin Station, Eaux-Vives Station and Annemasse (CEVA) is currently under construction including a cut-and-cover tunnel built by slurry walls located in the alluvium of the Foron River. The covered trench cuts the groundwate ...

Experimental Study at Prototype Scale of a Self-priming Free-Surface Siphon

Giovanni De Cesare, Paloma Furlan

This study is within the frame of the construction of the rail link between Geneva Cornavin station, Eaux-Vives station and Annemasse (CEVA). The project area is located at a cut-and-cover tunnel built by slurry walls located in the alluvium of the Foron R ...

Geometry as a Catalyst: How Vapor Cavities Nucleate from Defects

Simone Meloni

The onset of cavitation is strongly enhanced by the presence of rough surfaces or impurities in the liquid. Despite decades of research, the way the geometry of these defects promote the nucleation of bubbles and its effect on the kinetics of the process r ...

Chute Aerators : Steep Deflectors and Cavity Subpressure

Michael Pfister

Chute aerators are applied to high-velocity spillways to entrain air into the flow so that cavitation damage is avoided. Air entrainment occurs locally at the aerator, whereas further downstream the flow is deaerated. This process is relevant because it de ...

Techniques for generating centimetric drops in microgravity and application to cavitation studies

Mohamed Farhat, Philipp Kobel, Danail Obreschkow, Nicolas Dorsaz, Philippe Kobel

This paper describes the techniques and physical parameters used to produce stable centimetric water drops in microgravity, and to study single cavitation bubbles inside such drops (Parabolic Flight Campaigns, European Space Agency ESA). While the main sci ...
