    • Added mass effects on a Francis turbine runner with attached blade cavitation 

      Huang, Xingxing; Escaler Puigoriol, Francesc Xavier (Multidisciplinary Digital Publishing Institute (MDPI), 2019-06-11)
      Article
      Open Access
      To have a safe structural design, an analysis of the dynamic behavior of a Francis turbine runner with consideration of the added mass e ects of surrounding water is necessary during design phase. Both in design and at o ...

    • Analysis if the dynamic response of pump-turbine runners- Part I: Experiment 

      Presas Batlló, Alexandre; Valero Ferrando, Ma. del Carmen; Egusquiza Estévez, Eduard; Huang, Xingxing; Farhat, Mohamed; Avellan, François (2012)
      Conference report

      When in operation, pump-turbine runners have to withstand large pressure pulsations generated by the rotor-stator interaction. The analysis of the dynamic behavior of these structures is necessary to avoid damage. For this ...

    • Analysis of the dynamic response of pump-turbine impellers. Influence of the rotor 

      Egusquiza Estévez, Eduard; Valero Ferrando, Ma. del Carmen; Presas Batlló, Alexandre; Huang, Xingxing; Guardo Zabaleta, Alfredo de Jesús; Seidel, Ulrich (2016-02-01)
      Article
      Open Access
      This paper deals with the dynamic response of pump-turbine impellers. A pump-turbine impeller is a complex structure attached to a rotor and rotating inside a casing full of water with very small clearances between the ...
