The 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, ...

Modeling of rough contact interfaces with trapped compressive liquid pockets

Jean-François Molinari, Guillaume Anciaux, Parissasadat Alavi, Julie Richard, Loris Rocchi

Boundary and mixed lubrication are usually used to reduce friction in sheet metal form- ing. In the boundary lubrication regime load is mainly carried by contacting asperities. Therefore, the tribological problem can be solved in the dry case using a geome ...

Gondo Throttled Surge Tank Numerical Modeling and Design Review

Mona Seyfeddine

In order to increase the installed capacity, the refurbishment of Gondo high-head power plant required a modification of the existing surge tank by installing a throttle at its entrance. In a previous study, the geometry of this throttle was optimized by p ...

Hybrid modeling and design review of throttled surge tanks

Giovanni De Cesare, Samuel Luke Vorlet, Nicolas Jean François Pascal Ghislain Adam, Mona Seyfeddine, Bernard Valluy

The 2050 Swiss Energy Strategy aims to increase the annual production of hydroelectricity by 4% while 90% of the technically feasible potential is already used. The flexibility of high-head storage power plants (HPP), the main pillar of Swiss peak electric ...

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 ...

Modelling cell seeding to homogenize cell distribution within scaffold for tissue engineering

Nathanel David Apter

Cell Seeding is a key factor for good regeneration in tissue engineering. In order to ensure uniform tissue regeneration, a system has to be found to distribute cells evenly within the scaffold that will carry them in the body. In this extent, this work tr ...

Open-loop control of a separated boundary layer

François Gallaire, Edouard Boujo

Linear optimal gains

G_{opt}(\omega)

are computed for the separated boundary-layer flow past a two-dimensional bump in the subcritical regime. Very large values are found, making it possible for small-amplitude noise to be strongly amplified and to desta ...
