An Analysis on Performance of the Archimedes Screw Turbine – A Review of Past Studies

Archimedes screw turbines are a novel type of small hydroelectric power plant that can be used in low-altitude locations. The Archimedes screw turbine is a clean and renewable energy source and is safer for wildlife and especially aquatic life than other hydroelectric generation options. In addition to other sources of energy, the turbine is not a definitive and comprehensive solution. However, it can have many economic, social and environmental benefits. This makes this device an effective option for sustaining hydropower development. Archimedes screw turbines can produce up to 355 kW of power at low water heads (less than about 5 meters) and a range of flow rates with a practical efficiency of 60% to 80%. This device can be operated in remote areas and small communities. Therefore, it increases the potential for the sustainable development of hydropower. In many low-head situations, the Archimedes screw turbine is more cost-effective than alternative hydroelectric systems with less installation and operating costs. Also, disturbances in sedimentation and natural erosion processes and the performance of wildlife, especially aquatic animals, are associated with a significant decrease. Archimedes screw turbines can be operated at the lowest flow rate in the majority of chain power plants and outside the power generation network. This article examines the characteristics of the Archimedes screw turbine and examines its operation methods and its features and disadvantages.
