    An experimental investigation has been carried out to evaluate the performance of a cavitating Venturi flow. For that purpose, a closed loop circuit with a centrifugal pump and a transparent asymmetric converging-diverging ...
  • Film boiling heat transfer from micro heat sinks driven by Bénard-Marangoni convection 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (2021-01-26)
    External research report
    Open Access
    Bénard-Marangoni convection and its significance with regard to film boiling heat transfer from micro heat sinks is discussed. In recent works cooling performance of micro heat sinks has been studied showing that two-phase ...
  • Magnetic hyperthermia for particle image velocimetry (MH-PIV) 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (2021-01-26)
    External research report
    Open Access
    In this work a novel approach is investigated for Particle Image Velocimetry (PIV) which is a technique used as optical method for instantaneous flow visualization. So far traditional PIV is based in the injection of small ...
  • Ferrofluid moving thin films for active flow control 

    Arias Montenegro, Francisco Javier (Elsevier, 2021-01-12)
    Article
    Open Access
    Ferrofluid moving thin films and their possible significance with regard to active flow control for lift and attack angle enhancement are discussed. In this strategy, a very thin film of ferrofluid is strongly attached at ...
  • Numerical investigation of the cavitation effects on the vortex shedding from a hydrofoil with blunt trailing edge 

    Chen, Jian; Geng, Linlin; Escaler Puigoriol, Francesc Xavier (Multidisciplinary Digital Publishing Institute (MDPI), 2020-11-21)
    Article
    Open Access
    Vortex cavitation can appear in the wake flow of hydrofoils, inducing unwanted consequences such as vibrations or unstable behaviors in hydraulic machinery and systems. To investigate the cavitation effects on hydrofoil ...
  • Numerical modal analysis of a Kaplan turbine runner 

    Roig Bauzà, Rafel; Torre Rodríguez, Óscar de la; Jou Santacreu, Esteban; Escaler Puigoriol, Francesc Xavier (2020)
    Conference lecture
    Open Access
    The aim of the research has been to investigate the change of dynamic behavior of a Kaplan turbine runner when submerged in still water. More specifically, the effects of the added mass on the modes of vibration have been ...
  • Improvement of cavitation mass transfer modeling by including Rayleigh–Plesset equation second order term 

    Geng, Linlin; Chen, Jian; Escaler Puigoriol, Francesc Xavier (2020-06-03)
    Article
    Restricted access - publisher's policy
    The current study evaluates the effect of taking into account the second order term of the Rayleigh– Plesset equation for the numerical simulation of cavitation with homogeneous mixture models. For that, the corrected ...
  • Airplane vortices evolution near ground
