Abstract


Archimedes screw turbine is a type of turbine for generating micro-hydro electric energy which is sourced from water. Initially, Archimedes screw was only used as a tool to transport water from rivers or streams. But nowadays many researchers are starting to see the potential of Archimedes screw which can be used as a turbine for generating electricity, this is because Archimedes screw can work even with a small amount of water discharge, has good efficiency at small discharge and low head, but when using a turbine will cover the entire water flow so that all water discharge enters the turbine, which if the water flow overflows it will submerge the turbine so that the turbine cannot working and can cause damage. Therefore this study aims to overcome this by providing flotation to the turbine so that it continues to work if the water flow overflows, and also aims to find the turbine variant with the most efficient number of blades using the CFD simulation method. By using a turbine with a long dimension of 180mm, a turbine diameter of 42mm, a turbine shaft diameter of 12.6mm. The results obtained from the CFD simulation show that the turbine with the 1 blade variant is the best variant, producing a turbine rotation of 518.3 rpm, torque of 0.00473 Nm, power of 0.257 watts and efficiency reaching 72.12% and errors from the simulation results with turbine test results directly less than 5%.
