Abstract
A hydraulic turbine with increased power capacities for new or existing hydroelectric installations. The turbine has a larger axial runner wheel and a reshaped runner ring peripherally extending around the runner wheel. A draft tube with a larger elbow section extends on a downstream side of the runner ring. A water supply port extends around a rotation axis of the runner wheel on an upstream side of the runner ring, and is adapted to produce a centripetal water flow swirling around the rotation axis of the runner wheel. A turning passageway extends between the water supply port and the runner ring, and is adapted to guide and redirect the centripetal water flow in a substantially axial direction of the runner wheel. An axial distributor extends between the turning passageway and the runner ring.
