Effect of Air Injection on the Internal Flow Characteristics in the Draft Tube of a Francis Turbine Model
Under low flow-rate conditions, a Francis turbine exhibits precession of a vortex rope with pressure fluctuations in the draft tube. These undesirable flow phenomena can lead to deterioration of the turbine performance as manifested by torque and power output fluctuations. In order to suppress the r...
