This paper presents an experimental investigation of flow phenomena related to the characteristic frequencies of pressure fluctuation in Francis hydroturbine models. The experiments were carried out on two test rigs with two model runners having hydraulic similarities. Flow structures at the inlet region of runner and in draft tube at different operating conditions were visualized on another hydrodynamic test rig. Analyses of dominant frequency of unsteady hydraulic behaviors in the tested hydroturbines were performed.

Chapter 2 Francis Hydro Turbine
Turbines using the impulse action of water are the best ones. Francis, an American civil engineer comes up with his turbine called Francis turbine. He is just mixing them up. The magic lies in his amazing design of blades, these blades rotate using both reaction and impulse force of water flowing through them.
The X-Blade runner technology has been designed to provide improved stability over large ranges in flow and head, as well as strong cavitation behaviour and higher efficiency levels. Expected to be completed in , the project is designed to provide higher efficiency, a greater range of stable operation, and reduced maintenance costs for the hydro plant. The upgraded units at Mossyrock are expected to each have unique performance curves, enabling them to more efficiently cover the full operating range of the plant. The desired result will be increased energy production for Tacoma Power.
