Abstract The present work is carried out to study the performance of a Savonius rotor for small-scale hydropower generation. It has been observed that some of the irrigation channels available in the rural areas are having enough bed slope to generate kinetic energy, which can be harnessed through a Savonius rotor. An in-house fabricated scale-down model of the Savonius rotor is tested at an inclination of the re-circulating indoor multipurpose tilting flume at 0°, 0.5°, 1.0°, 1.5° and 2.0° to determine performance under controlled conditions. It is observed that at the tip speed ratio of 0.92 and channel inclination of 0.5° compared to 0° inclination, the coefficient of power and coefficient of torque improved to 40% and 10%, respectively. Furthermore, it is found that the torque and power developed by the turbine are maximum at a bed slope of 2.0° owing to the maximum available energy.

垂直轴水轮机在不同河床坡度灌溉渠道可持续发电的应用研究

摘要 目前的工作是研究用于小型水力发电的Savonius 转子的性能。据观察，农村地区的一些灌溉渠道有足够的河床坡度来产生动能，可以通过萨沃尼厄斯转子加以利用。内部制造的 Savonius 转子缩小模型在 0°、0.5°、1.0°、1.5° 和 2.0° 的再循环室内多用途倾斜水槽的倾斜度下进行测试，以确定受控条件下的性能。观察到在 0.92 的叶尖速比和 0.5° 的通道倾角与 0° 倾角相比，功率系数和扭矩系数分别提高到 40% 和 10%。此外，发现涡轮机产生的扭矩和功率在床坡度为 2 时最大。
