Francis-99 workshop 1: Steady state operation

Francis-99 is the series of workshops that provided open data to the researchers worldwide. Hydraulic turbines play essential roles to mitigate the renewable energy demand. The design data of the turbine are rarely available due to confidentiality. The workshop series provides an unique opportunity to the researchers worldwide and provides the state-of-the-art measurement data with computational model.

The data contains experimental results of the mode Francis turbine in the Waterpower laboratory, NTNU. The provided data can be used to define boundary conditions and validation of the computational fluid dynamic model. The data also contains the computational fluid dynamic model. The dataset corresponds to the first workshop of the Francis-99.

The data includes both pressure measurements at selected locations in the turbine and velocity measurements in draft tube. Velocity was measured using PIV in the draft tube. The measurement data contains three operating points: (1) BEP - design load (2) part load and (3) high load. A potential user can use these data and validate the numerical simulation model. Detailed information about the data is available in the attached report.
