Detection and analysis of part load and full load instabilities in a real Francis turbine prototype
(Institute of Physics (IOP), 2017)
Text en actes de congrés
Accés obertFrancis turbines operate in many cases out of its best effici ency point, in order to regulate their output power according to the instantaneous ener gy demand of the grid. Therefore, it is of paramount importance to analyse ... -
Overview of the experimental tests in prototype
(Institute of Physics (IOP), 2017)
Text en actes de congrés
Accés obertExperimental tests in prototype are necessary to understand the dynamic behaviour of the machine during different operating points. Hydraulic phenomena as well as its effect on the structure need to be studied in o rder ... -
Dynamic response of the MICA runner. Experiment and simulation
(Institute of Physics (IOP), 2017)
Text en actes de congrés
Accés obertStudying the dynamic response of Francis turbine runners is of paramount importance in order to avoid resonance problems during operating conditions. For this purpose, the natural frequencies as well as their associated ... -
