Research activities

Extension of the hydraulic turbines operating range to provide electrical power system flexibility & stability for the integration of renewables; Fundamental cavitation research and development of numerical tools.



XFLEX aims to demonstrate an innovative methodology for system integration of hydroelectric technology solutions, variable speed being a key component and a reference, to provide further enhanced flexibility services assessed by a crosscutting analysis of their impact on both the technology and the market aspects.


The proposed multi-disciplinary project aims to develop a numerical tool for assessing the true hydropower renovation potential of these hydropower stations by considering both electricity generation increase and services to the grid.

Duo Turbo

The project focuses on turning a counter rotating micro-turbine proof of concept into a range of standard energy recovery stations able to harvest energy on drinking water networks


the project aims to study the hydraulic, mechanical and electrical dynamics of several hydraulic machines configurations – fresh and seawater turbines, reversible pump-turbines – under an extended range of operations : from overload to deep part load. A two-pronged modelling approach will rely on numerical simulations as well as reduced-scale physical model tests.


SPHEROS is a particle-based code, which stands on SPH and erosion. The code is developed at LMH to simulate free-surface flows in hydraulic machines and specifically silt erosion phenomena occurring in Pelton turbines.
