Abstract

The invention relates to a hydraulic turbine, in which the inflow of water is directed tangentially in a first plane perpendicular to its axis as far as the centre of the turbine wheel and subsequently parallel to the axis of the wheel before exiting tangentially in another plane perpendicular to the axis of the wheel. In the inflow phase, efficiency is enhanced by diversion and deceleration of the flow, whereas in the outflow phase efficiency is enhanced by diversion and acceleration of the flow. The method of the invention comprises the following steps: 1. inflow at high speed, in the form of jets, tangentially to the outside diameter of the wheel; 2. diversion of the flow by 90°; 3. deceleration of the flow; 4. reversal of the direction of flow; 5. acceleration of the flow; 6. diversion of the flow by 90°; 7. outflow at high speed, in the form of jets, tangentially to the outside diameter of the wheel.
