  • Large Eddy Simulation of the transient cavitating vortical flow in the wake of a hydrofoil 

    Chen, Jian; Geng, Linlin; Escaler Puigoriol, Francesc Xavier (2021)
    Conference report
    Open Access
    The Zwart mixture cavitation model and the Large Eddy Simulation (LES) turbulence model have been combined to simulate the transient cavitating flow in the wake of a hydrofoil. The hydrofoil is a 2D NACA0009 with a truncated ...
  • Novel flux-weakening strategy considering the saturation effects for electric vehicles 

    Miguel Espinar, Carlos; Heredero Peris, Daniel; Subirats Rillo, Oriol; Escaler Puigoriol, Francesc Xavier; Montesinos Miracle, Daniel (2021)
    Conference report
    Open Access
    This paper proposes an innovative control algorithm for Permanent Magnet Synchronous Machines (PMSMs), based on a Vector Current Control (VCC) strategy in order to operate in the Flux-Weakening (FW) zone and a Finite Element ...
  • Numerical investigation of the effects of hydrofoil vibrations on the unsteady behavior of cavitation 

    Geng, Linlin; Chen, Jian; Torre Rodríguez, Óscar de la; Escaler Puigoriol, Francesc Xavier (Institute of Physics (IOP), 2021)
    Conference report
    Open Access
    In order to better understand the fluid-structure interaction (FSI) in hydraulic machines, this study aims to numerically investigate the flow around an oscillating hydrofoil with special attention on the effect of ...
  • Measurement of the Influence of Sheet Cavitation on the Heat Generated in a Closed Loop Pumping System 

    Bermejo Plana, David; Escaler Puigoriol, Francesc Xavier; Dular, Matevž; Ruiz Mansilla, Rafael (2021)

    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 ...
