Despite the increasing popularity of Archimedes screw turbines for micro-hydropower plant applications around the world, its current status in the Philippines remains underdeveloped. The researchers investigated the potential of utilizing an Archimedes screw turbine for energy generation in the country. The design of a scaled-down Archimedes screw turbine for testing site parameters was based on the works “The Turn of the Screw: Optimal Design of an Archimedes Screw” by Chris Rorres and “Modeling and Experimental Results of an Archimedes Screw Turbine” by Rohmer, Knittel, Sturtzer, Flieller, and Renaud, where the researchers came up to use a 3-blade screw turbine. All the calculations and considerations, important parameters were defined and used in a CAD (computer-aided design) software. An expected power output of 212 W was calculated. Material selection and acquisition came after the design. Then, fabrication of the screw turbine and the assembly of the micro-hydropower plant were done. The testing procedure for the constructed Archimedes screw turbine run-of-river system micro-hydropower plant was conducted and an actual output peak power of 198 W was obtained. The researchers were able to conclude the validity of the aforementioned works, and the design of a 5-kW Archimedes screw turbine was obtained for the power plant site in Laiban river located at Laiban, Tanay, Rizal.
