Investigation of the Time Resolution Set Up Used to Compute the Full Load Vortex Rope in a Francis Turbine
François Avellan, Cécile Münch-Alligné, Arthur Tristan Favrel, Andres Müller
The flow in a Francis turbine at full load is characterised by the development of an axial vortex rope in the draft tube. The vortex rope often promotes cavitation if the turbine is operated at a sufficiently low Thoma number. Furthermore, the vortex rope ...
2021Numerical simulations of Pelton turbine flow to predict large head variation influence
François Avellan, Cécile Münch-Alligné, Siamak Alimirzazadeh, Steve Crettenand
In the framework of the new feed-in-tariff system in Switzerland for Small Hydropower Plants (SHP), the aim of the SmallFLEX project, led by HES-SO Valais and performed in collaboration with EPFL, WSL, EAWAG, PVE, and FMV, is to show how SHP can provide wi ...
IOP PUBLISHING LTD2021CFD simulations of a Y-junction for the implementation of hydraulic short-circuit operating mode
François Avellan, Cécile Münch-Alligné, Daniel Biner
In the framework of the XFLEX HYDRO H2020 European Project, one of the demonstrators focuses on the implementation of the hydraulic short-circuit on the pump storage power plant of Grand-Maison owned by Electricite De France (EDF). The Grand-Maison power p ...
IOP PUBLISHING LTD2021DuoTurbo: Implementation of a Counter-Rotating Hydroturbine for Energy Recovery in Drinking Water Networks
François Avellan, Cécile Münch-Alligné, Vlad Hasmatuchi, Daniel Biner, Samuel Chevailler
To enhance the sustainability of water supply systems, the development of new technologies for micro scale hydropower remains an active field of research. The present paper deals with the implementation of a new micro-hydroelectric system for drinking wate ...
2021Experimental and numerical investigations of a high-head pumped-storage power plant at speed no-load
François Avellan, Pedro Filipe De Almeida Manso, Cécile Münch-Alligné, Vlad Hasmatuchi
Due to the increasing integration of new renewable energies, the electrical grid undergoes more frequent instabilities. Hydroelectric power plants, particularly pumped storage plants, are well suited for grid control. However, this objective requires exten ...
IOP PUBLISHING LTD2019Hydraulic performance evaluation of a micro-turbine with counter rotating runners by experimental investigation and numerical simulation
François Avellan, Elena Vagnoni, Cécile Münch-Alligné, Loïc Andolfatto
The development of energy recovery systems on existing water utility networks is a new challenge for increasing the sustainability of electricity generation mix. The concept of the new micro-turbine with counter rotating runners braces this goal by allowin ...
2018Comprehensive power loss modelling to improve the performance of an Energy Recovery Station for water utility networks
François Avellan, Cécile Münch-Alligné, Loïc Andolfatto, Daniel Biner
The work presented in this paper details the methodology applied to inventory and estimate the power losses in a micro-turbine with counter-rotating runners. The separation between the impact of design parameters and operational parameters on each identifi ...
Pennwell2017Experimental characterization of a five blade tubular propeller turbine for pipe inline installation
Anton Schleiss, Cécile Münch-Alligné, Mário Jorge Rodrigues Pereira Da Franca, Vlad Hasmatuchi, Irene Almeida Samora
The interest in micro-hydropower in existing infrastructure is increasing since this is a technology with low environmental impacts and potential for energy recovery in different types of installation. The technologies available for these schemes are still ...
Elsevier2016Energy production with a tubular propeller turbine
Anton Schleiss, Cécile Münch-Alligné, Mário Jorge Rodrigues Pereira Da Franca, Vlad Hasmatuchi, Irene Almeida Samora
Micro-hydropower is a way of improving the energetic efficiency of existent water systems. In the particular case of drinking water systems, several studies have showed that pressure reducing valves can be by-passed with turbines in order to recover the di ...
2016Simulation of energy recovery on water utility networks by a micro-turbine with counter-rotating runners
François Avellan, Elena Vagnoni, Cécile Münch-Alligné, Loïc Andolfatto, Vlad Hasmatuchi
Wherever relief valves and other energy dissipation devices are installed to limit the pressure, water utility networks provide unexploited hydropower potentials. This is mainly due to a lack of economically viable technologies for energy recovery in the p ...
