Simulation 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 ...
