    The so-called hydrodynamic heat generators are claimed as high efficiency heating devices, avoiding scaling by warming liquids without transfer surface with the help of cavitation effects. However, neither the mechanisms ...
  • Numerical assessment of parameters influencing the modal response of a Kaplan turbine model 

    Roig Bauzà, Rafel; Torre Rodríguez, Óscar de la; Jou Santacreu, Esteban; Escaler Puigoriol, Francesc Xavier (Institute of Physics (IOP), 2021)
    Conference report
    Open Access
    The present study intends to investigate numerically the impact of: i) the fluid added mass, ii) the turbine rotational speed and iii) the variation of the runner blade bearing stiffness due to the turbine water head on ...
