Abstract

A runner for a hydraulic turbine or pump has a plurality of blades. Each of the blades is defined by a pressure surface, an oppositely facing suction surface, a leading edge and a spaced-apart trailing edge. At least one of the blades has a device for supplying a flow of oxygen containing gas to the trailing edge of the same blade. The device includes at least two separate gas inlet apertures and at least two separate gas passages, each extending from one of the separate gas inlet apertures to a separate group of orifices in the trailing edge of the same blade. Each of the separate group of orifices has at least one orifice to admit gas out of the corresponding separate gas passage to the passing fluid during the operation of the runner.
