Description
In general intake facilities of hydroelectric power stations, intake vortices cause the air-hammer phenomena in the intake tunnel and the cavitation phenomena at blades of a water turbine generator by air-entrainments. In order to understand hydraulic characteristics of a vortex-suppressing device in a vertical intake facility, flow fields in the basic model of a vertical intake facility that combined a rectangular linear channel and a vertical pipe have been measured using a Particle Tracking Velocimetry (PTV). As a result, the relationship between installation positions of a vortex-suppressing device and number of occurrences of intake vortices indicates that the vortex-suppressing device installed near free surface and near vertical pipe is more effective.
