This paper presents a new type of hydraulic reactive turbine with radial wicket gates (gates having pivotal axes parallel to the turbine axis) designated the {open_quotes}Potential Flow Turbine{close_quotes}. The runner in this turbine could be axial. as in a Kaplan turbine, or mixed flow, as in a Francis turbine. The wicket gates in the Potential Flow Turbine are capable of both regulating and closing off flow to the water passages. At the same time they have a shape providing the flow with constant whirl at the entrance to the runner for the design conditions and, therefore, the correspondingly designed runner delivers to the draft tube the flow with whirl equal to zero. The new turbine has improved efficiency and cavitation coefficient, {rho}.
