Abstract
There is disclosed a new cavitation free hydraulic turbine system which fully utilizes well-established hydrodynamic theories useful for low-head hydroelectric applications. The hydropower turbine system of the present invention makes use of a fixed blade propeller turbine with reverse blade angle and an upward flow passage. To eliminate the complex flow control adjustable vane system and elaborate tube design and construction of the prior art, the new turbine system is provided with a vertical needle valve and a near zero absolute velocity free exit flow design.
