能源需求不断增长，特别是在发展中国家。水电等可再生能源已成为清洁发电最需要的能源之一。由于地形复杂等原因，在无法进行电网扩建的地区，需要建设低水头水电站。重力式水轮机是一种低水头涡轮机，它是将自由表面流动的水沿切向通过水池，形成水涡流，从而将机械能转化为动能。本研究分析了不同的水池结构，这些结构具有从低水头、低流量水流形成重力涡流的能力，并具有在水池中的最佳转轮位置，以最大化输出功率。首先通过使用CAD软件SolidWorks开发模型进行分析，并在商业CFD代码ANSYS Fluent中进行模拟以测量速度。其次，通过测量输出功率对所得到的结果进行了实验验证。
Demand of energy is ever increasing, especially in developing countries. Renewable energy such as hydropower has become one of the most demanded sources of energy for its clean generation. Low head hydropower plant is demanded in area which cannot see grid extension due to difficult geographical terrain and other reasons. Gravitational water vortex power plant is one of such low head turbine in which the mechanical energy of free surface flowing water is converted to kinetic energy by tangentially passing the water to a basin, which forms a water vortex. This study is the analysis of different basin structures which has ability to form a gravitational vortex stream from low head, low flow water streams with the optimum runner position in the basin to maximize the output power. The analysis was first carried out by development of the model using CAD software, SolidWorks and it was simulated in commercial CFD code ANSYS Fluent for the measurement of velocity. Secondly, the result so obtained was experimentally verified by measuring the output power.
