A mixed standard/custom design strategy to minimize cost and maximize efficiency for picohydro power potential harvesting

François Avellan, Elena Vagnoni, Cécile Münch-Alligné, Loïc Andolfatto

Harvesting the numerous small scale hydroelectric potential is a way to increase the sustainable hydraulic energy production in developed countries. The condition to meet economical profitability with pico power stations - below 25 kW - is to minimize the ...

Pressure measurements and high speed visualizations of the cavitation phenomena at deep part load condition in a Francis turbine

François Avellan, Arthur Tristan Favrel, Christian Landry, Andres Müller, Keita Yamamoto

In a hydraulic power plant, it is essential to provide a reliable, sustainable and flexible energy supply. In recent years, in order to cover the variations of the renewable electricity production, hydraulic power plants are demanded to operate with more e ...

Fabrication of high adhesion cm-scale compliant electrodes for dielectric elastomer transducers using O2 plasma activation

Herbert Shea, Samuel Rosset, Oluwaseun Adelowo Araromi

We present a novel methodology for the production of PDMS-carbon powder electrodes with high adhesion for dielectric elastomer (DE) transducers. DE transducers have received significant interest in recent years due to their potential as stretchable-flexibl ...

Mathematical modelling of swirling flow in hydraulic turbines for the full operating range

François Avellan

We introduce and validate a novel mathematical model for computing the radial profiles of both axial and circumferential velocity components, respectively, of the swirling flow exiting the runner of hydraulic turbines within the full operating range. We as ...
