Lab testing and consulting services

EPFL LMH …

…is the leading independent laboratory for experimental validations of reduced scale models for new hydropower projects or turbine refurbishments in accordance with the IEC60193 standard.

Facilities

Three Test Rigs for research and development of Hydraulic Turbines, Storage Pumps and Pump-Turbines.

  • State of the art research facility, utilizing the latest measuring instruments and technical advancements to produce data that easily and consistently complies with all IEC 60193 standards
  • 3 fully modular test rigs can be adjusted to fit just about every type of hydraulic turbine, storage pump and pump-turbine
  • Automated test rig processes and years of testing experience allow for quick performance assessment, potentially shortening development times without diminishing quality
  • Each test rig is fully independent from the other, allowing for uninterrupted parallel testing.

The cavitation tunnel installed at the Laboratory for Hydraulic Machines provides high speed visualization of various types of cavitation phenomena, including leading edge cavitation, wake cavitation, and tip vortex :

  • Cavitation nuclei control
  • 5 components load cell
  • Optical instrumentation: particle image velocimetry, Laser Doppler velocimetry
  • High speed visualization
  • Pressure transducers
