Abstract
In Uruguay, the potential for small, mini and micro scale hydropower has not been exploited yet, being the high investment costs the main reason. In order to overcome this issue and enhance the development of mini and micro hydropower in the country, the Hydropower group of Universidad de la República (Uruguay) decided to demonstrate the technical and economic feasibility of designing and manufacturing a propeller turbine with national capacities. Furthermore, it was believed that the existence of a test rig for scale model turbine evaluation in the facilities of a public university would be of great relevance for the enhancement of micro hydropower in the country. The hydraulic, mechanical and electrical installations of the test rig are presented, together with the acquisition system. The limitations of the test rig, owed to the dimensions of the piping and the ranges of the instruments within the acquisition system, are stated. The test rig is complemented with a SLA 3D printer for rapid turbine prototyping. The installation will serve not only for evaluation of the designed turbine within the current project, but also for the evaluation of future designs, teaching and other research activities of the university.
