Optimización del perfil hidráulico de un rodete tipo Francis de la Central Hidroeléctrica San Francisco

Abstract

The research work is based on the bibliographic and field methodology, the research method used was experimental, to complete the optimization method, five experiments were carried out in which variations were made in its geometric dimensions, to execute a computational study Using computational fluid dynamics in the virtual laboratory of the CIRT turbine research and recovery center, the main study parameters were the thickness of the blade, as well as the fluid inlet and outlet angles in relation to the impeller, resulting in efficiency produced by the impeller in each of the experiments performed. With these experiments, it was possible to conclude that, by modifying to the opposite direction of the main inlet curvature of the blade, the efficiency value can be increased, reducing turbulence along the path of the fluid on the surface of the blade, which improves the hydrodynamic properties, thus lengthening the useful life of the turbine.
