Nile River is considered as an auspicious area; in particular along with Upper Egypt, to produce electrical energy from the water current which called hydrokinetic energy. This sort of renewable energy is admitted deeply as a unique and uncommon solution for the electric power demand in the remote areas on the rivers’ sides. The hydrokinetic energy of the river stream can be extracted by a submerged vertical axis turbine due to its specific advantages. The main objective of this work is to investigate experimentally the performance of two different Savonius rotor profiles inside an irrigation canal in Toshka, Aswan, Egypt. Furthermore, the rotor with the optimum performance is investigated numerically by adding two shielding plates to further enhancements. The results indicate that the rotor with better fullness has better operating characteristics with a power coefficient 0.1285 at a tip speed ratio of 0.61 that is higher than the other rotor profile by 12%. Moreover, the two shielding plates increased the net average power coefficient at a tip speed ratio at 0.7 for the optimum rotor profile by 84% compared with the conventional design.

尼罗河被认为是一个吉祥地区。特别是与上埃及一起，从水流中产生电能，称为水动能。这种可再生能源已被广泛认为是解决河边偏远地区电力需求的独特且不常见的解决方案。由于其特殊的优势，可以通过浸没式垂直轴涡轮机提取河流的水动能。这项工作的主要目的是通过实验研究埃及阿斯旺Toshka灌溉渠内两种不同的Savonius转子轮廓的性能。此外，通过增加两个屏蔽板以进一步增强，对具有最佳性能的转子进行了数值研究。结果表明，具有较高填充度的转子具有更好的运行特性，在叶尖速比为0.61时的功率系数为0.1285，比其他转子分布曲线高12％。此外，与传统设计相比，对于最佳转子外形，两个屏蔽板在叶尖速度比为0.7时将净平均功率系数提高了84％。
