Diseño Paramétrico de Álabes para Turbina Francis

Abstract

The main objective of this project is to obtain a parametric design of hydrofoils for Francis turbines, in such a way that the user sets the input operative conditions of the system and, through a previously geometric method developed by Kristine Gjøsæter (Gjøsæter, 2011), the user obtains the Francis turbine hydrofoil geometry in an approximately way. This study also allows to obtain all the kinematic variables involved in the energy exchange process which occurs in the turbine rotor that is studied. For the project development purpose, Matlab was used in order to adapt the parametric model, and Ansys-CFX was used for the flow simulation on the hydrofoils obtained. The software presents two extra modules; the first one helps the students remembering the basic theoretical information for making the thermodynamic analysis, this module also lets the students work with a dry air thermodynamic properties calculator. The second one will evaluate after the Brayton cycle equipment testing.
