1. INTRODUCTION Nowadays, various studies have shown different methods to enhance the efficiency of the Savonius turbine (ST) and Darrieus turbine (DT) based on computational and experimental techniques, such as the variation of the design parameters of the turbine. The aspect ratio (AR), the gap distance, the vanes profile, and the number of the vanes are the prime parameters that affect the performance of ST and DT. Patel et al. (2017) presented an experimental investigation of a Savonius water turbine. They studied the impact of the AR, the gap distance and the end disk. They investigated various gap distances (From 0 to 0.174). For a piece gap distance, they tested different ARs. In conclusion, they noted that the performance parameters of the ST could be enhanced using end disks.....
