An experimental and theoretical investigation of the flow at the outlet of a Francis turbine runner is carried out in order to elucidate the causes of a sudden drop in the draft tube pressure recovery coefficient at a discharge near the best efficiency ope ...
This paper deals with 5-axis milling of hydraulic blades. The issue developed is essentially linked to problems due to the transition from 3 to 5 axes. A specific attention is done to the Inverse Kinematics Transformation (IKT) which can be source of incoh ...
Numerical and Experimental Analysis of Free Surface Flow in a 3D Non-Rotating Pelton Bucket Low frequency fluctuations often occur in hydraulic installations equipped with fixed bladed turbines or pumps operating under off design conditions. Passive measur ...
A common phenomenon in Francis turbines is draft tube surge. In these fixed-bladed machines, a strong runner outlet swirl can develop under off-design conditions. The action of the diffuser, and in particular the draft tube elbow, on the rotating flow fiel ...
GE Energy Hydro has developed a new procedure for the CFD analysis of the unsteady rotor-stator interaction between the wicket gates and runner blades of Francis turbines. The results from the CFD calculations have been successfully validated by means of h ...
Low frequency fluctuations often occur in hydraulic installations equipped with fixed bladed turbines or pumps operating under off design conditions. Passive measures, such as air ad- mission or minor design modifications, are commonly taken as a last reso ...
Three dimensional numerical tools are now commonly used in the design or analysis process of the internai flow of hydraulic machinery. As an illustration of the use of such tools to study the internai flow of a Francis turbine, the computational results ob ...

Stability of operation of Francis turbines Hydraulic disturbances often come with the operation of Francis turbines outside of design head and flow. In some cases, the excessive amplitude of the dynamic system response to these disturbances leads to res ...
The current work intends to improve the cavitation erosion prediction methodology in hydro turbines by the use of onboard vibration measurements taken on the rotating shaft. For that, a measuring campaign in two similar Francis turbine prototypes has been ...
