Design and analysis of gorlov helical hydro turbine on index of revolution

Abstract

Energy production in India during 2017–2018 has increased by 5.71%, while 7.39% in 2019, as per the Energy Statistics of India. Due to the ever-increasing demand, Renewable Energy Sources (RES) are used to meet the power demand with low cost and emission. In India, the power generation capacity of micro-hydropower is limited to 1.8% (19749 MW) of the total potential reserve. The conventional turbines may not effectively harness energy for the micro-hydropower system. Traditional turbines are ideally suited for applications requiring a low discharge with a high head or a high discharge with a low head. However, they are futile in ultra-low head implementations. In order to enhance the electricity production from perennial/tidal sources, the Gorlov Helical Turbine (GHT) is suggested. This paper presented a design and analysis of garlov helical hydro turbine on index of revolution. GHT with a diameter and height of 0.600 m is designed for a micro-hydropower system. Nine 3D-GHT's with a diameter and height of 0.600 m is modelled based on varying indices of revolution. The effect of the index of revolution on the performance of the GHT is examined through simulation, MATLAB and field-testing. By analysing the outcomes, it is observed that 0.25 remains the optimum value for the index of revolution of the helix. The output power obtained by MATLAB, SolidWorks simulation and field-testing is 1.175W, 0.951W and 0.657W, respectively.
