Effect of Fins on the Internal Flow Characteristics in the Draft Tube of a Francis Turbine Model
Undesirable flow phenomena in Francis turbines are caused by pressure fluctuations induced under conditions of low flow rate; the resulting vortex ropes with precession in the draft tube (DT) can degrade performance and increase the instability of turbine operations. To suppress these DT flow instab...
