CFD-based analysis of pumped storage power plants implementing hydraulic short circuit operations
Elena Vagnoni, Alessandro Morabito
Hydraulic short circuit (HSC), corresponding to the simultaneous operation of the pumps and turbines, enhances the power flexibility of a pumped storage power plant (PSPP). However, comprehensive analyses are imperative to guarantee a secure and reliable o ...
Elsevier Sci Ltd2024Twenty years of irrigation acclimation is driven by denser canopies and not by plasticity in twig- and needle-level hydraulics in a Pinus sylvestris forest
Charlotte Grossiord, Christoph Bachofen, Eugénie Isabelle Mas, Hervé Cochard, Alice Jacqueline Frédérique Gauthey, Alex Tunas Corzon
Climate change is predicted to increase atmospheric vapor pressure deficit, exacerbating soil drought, and thus enhancing tree evaporative demand and mortality. Yet, few studies have addressed the longer-term drought acclimation strategy of trees, particul ...
Oxford2024Study of flexible operating conditions in variable-speed hydraulic turbines : advanced models and experimental validation
This PhD thesis is framed within the XFLEX HYDRO project, funded by the European Union's Horizon 2020 research and innovation program under grant agreement No 857832. The ultimate objective of the XFLEX HYDRO project is to increase hydropower potential in ...
EPFL2024On the prediction of the induced damage by the start-up sequence of Francis turbines: On operational resilience framework
Mario Paolone, Christophe Nicolet, Elena Vagnoni, Martin Seydoux
The number of transient operations in hydraulic machinery connected to power grid, notably start-ups and shut-downs, has observed a substantial increase in recent decades, primarily driven by the global shift toward intermittent renewable energy sources. S ...
2024Structural impact of the start-up sequence on Pelton turbines lifetime: Analytical prediction and polynomial optimization
Mario Paolone, Elena Vagnoni, Aldo Leonardo Alerci
Hydropower plants play a crucial role in the power system facing ambitious renewable energy targets. Due to their inherent controllability, they are well suited to provide flexibility to the grid. However, an increased flexibility provision leads to a prol ...
2023Interlocking modular microfluidic cooling substrates for future high energy physics experiments
In high energy physics, semiconductor-based sensors are widely used in particle tracking applications. These sensors are typically glued on low-mass cooling substrates, which guarantee the correct thermal management and, at the same time, minimise their in ...
EPFL2023Enhancing Flood Resilience: Sediment Management in Le Bez Torrent
Giovanni De Cesare, Azin Amini, Romain Nathan Hippolyte Merlin Van Mol
In the canton of Bern, Switzerland, the “Le Bez” torrent is known for its flash floods, causing sediment and wood debris buildup in Villeret village settled on the alluvial fan. To mitigate this issue, a sediment/wood trap system is being implemented upstr ...
