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.

New hydraulic test rig for small-power turbomachines
A new universal test rig has been installed at the HES-SO VS Sion - Switzerland to assess the hydraulic performances of
different types of small-power turbomachines (up to 10 kW) and other hydraulic components with complex geometry,
following the IEC 60193 standard recommendations. The closed-loop circuit allows simulating different implantation levels
of the model and therefore recovering the cavitation performances as well.
The present work introduces a state-of-the-art approach of an automatic regulation for hydraulic test rigs. An autonomous
regulation system based on real-time measurements is developed using the capabilities of a National Instruments
compact Reconfigurable Input Output device. Indeed, during operation, the system can keep constant the value of the
desired parameters (e.g. testing head, discharge, pumps speed, Thoma number, etc.). Then, the implemented wireless
communication architecture between the hydraulic test rig and further measurements/monitoring systems offers flexibility.
Moreover, the control system of the test rig manages a dedicated cloud of variables and shares it with the client systems.
Finally, this approach ensures safe data centralization and storage on hydraulic turbomachinery model testing.
