Abstract
Hydrokinetic energy is a broadly available form of low-grade energy in countries like India, where irrigation canals are available in huge areas. To utilize this energy, hydrokinetic turbines are used. Out of many hydrokinetic turbines, efforts are made to improve Savonius hydrokinetic turbine's performance in the present work. The Savonius rotor profile is modified by providing a dual splitter-like shape on the blade's concave side. The two cases were selected for finding the optimum splitter position of both the splitter. The upper (top) splitter kept fixed and radially placed the second splitter in the first case. In the second case, the lower (bottom) splitter fixed and moving another splitter radially. Validated Computational analysis was done to analyze performance after modification. The fluid material was taken as water with standard properties. The improvement was observed for the specific position of splitters by 7.3% from conventional design.
