  • Modeling a high temperature PEM fuel cell focusing on its thermal behavior 

    Reija Chao, Uxía; Torres Cámara, Ricardo; Maria, Serra Prat (2017)
    Conference report
    Open Access
    The aim of this work is to develop a Computational Fluids Dynamics model using COMSOL Multiphysics, focusing on the thermal behaviour of a real HT-PEMFC . Energy management is the main concern as a better refrigeration ...

    Microwave and microfluidic techniques may enable wireless monitoring and interaction with bio-particles, yet still is a largely uncharted territory. Fortunately, the requirements of microfluidics and microwave techniques ...
  • Energy-preserving stable computations of high-pressure supercritical fluids turbulence 

    Bernades, Marc; Capuano, Francesco; Trias Miquel, Francesc Xavier; Jofre Cruanyes, Lluís (2022)
    Conference report
    Open Access
    High-fidelity computations of turbulent flows at high-pressure supercritical fluid conditions present significant challenges. Besides the inherent broadband nature of the flow, the rapid variation of thermophysical properties ...

    Aguilar Plazaola, José Agustín; Husar, Attila Peter; Andrade-Cetto, Juan (2021)
    Conference report
    Open Access
    The objective of the present work is to explore and validate autoregressive, control oriented models models Proton Exchange Membrane Fuel Cells coperatinf under dynamic condditions. Autoregressive models have several ...
  • Azimuthal waves and their stability in externally heated rotating spherical shells 

    Sánchez Umbría, Juan; García González, Fernando; Net Marcé, Marta (2011)
    Conference report
    Open Access
    Azimuthal waves appearing in the thermal convection of a pure fluid contained in a spherical shell with both boundaries at different temperatures are studied. They are computed by using continuation methods as steady ...
  • Stability analysis for the onset of convection in rotating fluid binary mixtures in spherical shells 

    Net Marcé, Marta; García González, Fernando; Sánchez Umbría, Juan (2011)
    Conference report
    Open Access
    The stability analysis of the basic conductive state of a rotating binary mixture of two fluids bounded by spherical shells is studied. The Boussinesq approximation of the mass conservation, Navier-Stokes, energy and ...
  • Near-interface modeling in large-eddy simulation of two-phase turbulent flow 

    Jofre Cruanyes, Lluís; Dodd, Michael S. (2020)
    Conference report
    Open Access
    The smallest hydrodynamic length scales in interfacial turbulent flow are located at the interface between phases/fluids as a result of two-way coupling phenomena. These interface-generated scales are, typically, several ...
