Manufacture and experimental evaluation of a hydrokinetic turbine for
remote communities in Colombia

E. Chica, Edwar A. Torres and J. Arbeláez




The manufacture and experimental evaluation of a hydrokinetic turbine of 1 kW are presented. A water velocity of 1.5 m/s, with a power coefficient of 0.4382, a tip speed ratio of 6.325, an angle of attack and pitch angle of 5 and 0 degrees, respectively, a blade length of 0.79 m, a drive train efficiency of 70% and a S822 hydrofoil profile were used for the design.
The blades were designed and manufactured by Computer Aided Design (CAD) and Computer Aided Manufacturing techniques (CAM) with a solid cross-section in order to provide the required strength. They were made of Prolon MS (Castnylon + Molybdenum). The platform that supports the
turbine was a modular floating raft simple to install, flexible, and durable made of high density polyethylene resin. The supporting structure of the turbine generator was made of stainless steel. The turbine was constructed of high quality and durable materials.
To determine the efficiency of the designed turbine, the electrical power and kinetic energy of the river were measured. The experimental assays of the turbine were performed in the Sinú River located in Córdoba (Colombia), obtaining an overall equipment efficiency of 0.5359.
