IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

ABSTRACT
The sustainability of the electricity mix can be increased by introducing recovery energy systems on existing water
supply infrastructures.
The concept of the new counter rotating micro-turbine presented in this work is a competitive option for energy recovery
on water utility networks. The micro-turbine performances and velocity fields have been predicted through a wide
Computational Fluid Dynamics (CFD) study. Experimental campaigns have been carried out to measure the
performance parameters and an experimental investigation on the flow velocity field characteristic of the new machine
was also performed.
2D Laser Doppler Velocimetry (LDV) measurements have been used in the counter rotating micro-turbine prototype
operating in water to explore and investigate the flow velocity field along with the prediction of the numerical simulations.
