AGUDELO, Sergio et al. Design, simulation, construction and characterization of a 5 kW hydraulic Pelton turbine . Ing. compet. [online]. 2013, vol.15, n.1, pp.183-193. ISSN 0123-3033.

It is presented the methodology for the construction of a 5 kW hydraulic microgenerator, with a Pelton turbine. For a given operating conditions (hydraulic head and flow) and from a theoretical and experimental basis, the different components were modeled using computational tools such as CAD (Computer Aided Design), CAE (Computer Aided Engineering) and CFD (Computer Fluid Dynamics). Subsequently, it was used a CAM (Computer Aided Manufactured) software and casting processes for manufacturing the components of the microgenerator. Finally, and in order to validate the design, characterization was performed by testing the microgenerator in the Laboratory of Alternative Energy Research Group at the Universidad de Antioquia. From the tests performed, it was possible to quantify the efficiency of the Pelton turbine, to find the optimum ratio between the opening of the nozzle and the generated power, the optimum speed of operation, the overall efficiency of the microgenerator and the hydraulic conditions in which the microgenerator can be used providing an optimal efficiency of electric power generation
