    Conference report
    Open Access
    To study the dynamic behavior of turbine runners (natural frequencies and mode shapes) not only the added mass effect of still water has to be considered. Also the effect of rotation may not be neglected in the dynamic ...
  • Boundary layer effects on the vortex shedding in a Donaldsontype hydrofoil

    Conference lecture
    Open Access
    La cavitación es un complejo fenómeno físico que se presenta generalmente en flujos turbulentos afectado por varios factores, como la presión del sistema y la concentración de gases no condensables disueltos. Para analizar ...
  • Estudio del fenómeno de interacción rotor estator (RSI) en una bomba radial, trabajando fuera de las condiciones de diseño óptimo 

    Coussirat Núñez, Miguel Gustavo; Fontanals García, Alfred; Panella, L; Guardo Zabaleta, Alfredo de Jesús (Asociación Argentina de Mecánica Computacional, 2014)
    Conference lecture
    Open Access
    El flujo en el interior de bombas radiales de altas prestaciones es difícil de describir, (geometría compleja y variable, flujo turbulento y no estacionario). La geometría compleja implica partes tanto móviles (rotor) como ...
  • Analysis of the dynamic response of pump-turbine runners. Part I: Experiment 

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