Abstract
Reaction hydraulic turbine that includes a draft tube having side wails arranged to define an inlet and an outlet and an elbow arranged to position the outlet substantially perpendicular to the inlet. A turbine runner is positioned adjacent the inlet and the outlet is arranged to define a flow exit, and a splitter vane is mounted within the draft tube to partially extend across a width of the draft tube. In this manner, flow is redirected about the elbow of the draft tube. The splitter vane includes opposing side edge surfaces that are spaced from the side walls, such that swirl flow is permitted around the splitter vane within the draft tube.
