Abstract

Ultra-low-head turbines can harness energy from previously deemed unsuitable sites, including natural and man-made locations like shallow estuaries, marine canals, and industrial waterways. Various hydro-turbine concepts were evaluated for their potential to extract power from these areas. These turbines can generate renewable energy for utilization in remotely located areas. A horizontal-axis screw turbine concept, horizontal and vertical Savonius turbine concepts, axial turbine concepts, and a gate turbine concept were investigated in the present study using computational fluid dynamic tools. Reynolds Averaged Navier Stokes equations with a shear stress transport model are used to calculate the flow field. The numerical methodology is then verified with previously published data. The turbine performances were compared and the design feasibility was analyzed to find the most effective turbine design which can extract the maximum energy. The gate turbine concept exhibited a significant power output with high efficiency while the screw turbine showed the lowest performance among the tested designs. The horizontal Savonius turbine displayed enhanced performance with an increment of 23.25 % compared to the screw turbine. An additional parametric study is conducted on the gate turbine namely, the number of runner blades, and the gate installation angle. The 3-bladed gate turbine installed at a 14° gate angle showed superior power output and efficiency than other hydrokinetic turbines.

摘要

超低水头水轮机可以利用以前被认为不合适的地点的能量，包括天然和人造地点，如浅河口、海运运河和工业水道。对各种水轮机概念从这些区域提取能量的潜力进行了评估。这些水轮机可以产生可再生能源，供偏远地区使用。在本研究中，使用计算流体动力学工具研究了水平轴螺旋水轮机概念、水平和垂直萨沃纽斯水轮机概念、轴流水轮机概念以及闸门水轮机概念。采用带有剪切应力输运模型的雷诺平均纳维-斯托克斯方程来计算流场。然后用先前发表的数据验证数值方法。比较了水轮机性能并分析了设计可行性，以找到能够提取最大能量的最有效水轮机设计。闸门水轮机概念表现出显著的功率输出和高效率，而螺旋水轮机在测试设计中表现出最低的性能。水平萨沃纽斯水轮机与螺旋水轮机相比，性能有所提高，增量为23.25%。对闸门水轮机进行了额外的参数研究，即转轮叶片数量和闸门安装角度。以14°闸门角度安装的三叶闸门水轮机比其他流体动力水轮机表现出更高的功率输出和效率。
