Archimedes Screw Turbine Performance: a review

Due to the increasing human need for electrical energy and the reduction of non-renewable resources for its production, the use of non-fossil and renewable resources and resources that have less environmental damage have been taken into consideration. Archimedes screw turbine is used as a means of producing clean energy in waterways, and many theoretical and experimental studies have been done on it. Most of these studies, in laboratory and numerical form, are in the field of optimization of screw constituent components and their effect on its efficiency including length, inner and outer diameter, installation angle, number of blades and screw pitch. In this research, the most important studies conducted in the field of Archimedes screw turbine performance, which have been published in the last two decades, were reviewed. The results showed that the parameters of screw components have a greater effect on efficiency compared to hydraulic parameters.
