ABSTRACT:
A deflector for use in a hydraulic turbine is adapted to be mounted relative to a vertically extending wall of the draft tube. The deflector has an upstream plate and a downstream plate. The upstream plate is positioned to extend downwardly and outwardly from the wall of the draft tube and the downstream plate is positioned to extend downwardly and inwardly from the upstream plate. The downstream plate has at least one elongated air communication port extending therethrough and adjacent the upstream plate. An air supply inlet portion extends from the wall of the draft tube into the deflector above the elongated air communication port permitting an oxygen containing gas to flow from the air supply inlet portion downwardly through the deflector, out the elongated air communication port and into the water flowing past the downstream plate so as to enhance the dissolved oxygen content of the water.
