Performance prediction of zero head turbine at different water levels

Abstract

Hydropower technology has been focusing on conventional water turbines with performance and efficiency depending on water head without really paying much attention to the energy in flowing waters. Such energy can be harnessed by integrating zero head turbines in possibly undershoot system. The turbines are modelled to be alternative systems in renewable energy. In this research, performance of this turbines in form of a conventional water wheel is studied using both programming prediction and experimental methods. Various type of turbines was designed by altering the blade inclination angle and testing the performance at 4- water levels. The maximum and minimum efficiencies were predicted in this study at this water levels. Based on the result, the viability of this turbines are positive and can be used to harness loss potential of flowing waters in canals and rivers which can be easily installed.
