This paper is aimed at exploring the performance characteristics of a simple reaction hydro turbine for power generation. Using principles of conservation of mass, momentum and energy, the governing equations have been identified for an ideal case of no frictional losses. The paper also describes the conception of a cross-pipe rotor for remote area electricity production. Using the ideal govern...

In this study, a Darrieus hydraulic turbine for power generation applications is chosen and the response surface methodology (RSM) based on central composite design (CCD) is applied to obtain the optimized design for its hydrofoil geometry to increase the torque coefficient. For this aim, all turbine performance factors, except hydrofoil geometry, were considered to be constant and the turbine ...

The hump feature is one of the major instabilities in pump-turbines. When pump-turbines operate in the hump region, strong noise and serious fluctuations can be observed, which are harmful to their safe and stable operation and can even destroy the whole unit as well as water conveyance system. In this paper, a low specific speed (nq = 36.1 min−1) pump-turbine model was experimentally investiga...
