    Article
    Restricted access - publisher's policy
    In deformed porous carbonates, the architecture of the pore network may be modified by deformation or diagenetic processes altering the permeability with respect to the pristine rock. The effects of the pore texture and ...
  • Dynamic modelling of an air-cooled LiBr-H2O absorption chiller based on heat and mass transfer empirical correlations 

    Farnós Baulenas, Joan; Castro González, Jesús; Papakokkinos, Giorgos; Morales Ruíz, Sergio; Oliva Llena, Asensio (2017)
    Conference lecture
    Restricted access - publisher's policy
    The paper describes the numerical modelling of a direct air-cooled single-effect absorption chiller and validates the obtained results by means of experimental data obtained from an own-designed and commissioned small ...
  • Study of hyperbranched poly(ethyleneimine) polymers of different molecular weight and their interaction with epoxy resin 

    Román Concha, Frida Rosario; Colomer Vilanova, Pere; Calventus Solé, Yolanda; Hutchinson, John M. (2018-03-09)

    Open Access
    Two different commercial hyperbranched poly(ethyleneimine)s (HBPEI), with molecular weights (MW) of 800 and 25,000 g/mol, and denoted as PEI800 and PEI25000, respectively, as well as the mixtures with a Diglycidyl Ether ...
  • Memory aware poisson solver for peta-scale simulations with one FFT diagonalizable direction 

    Oyarzun Altamirano, Guillermo; Borrell Pol, Ricard; Trias Miquel, Francesc Xavier; Oliva Llena, Asensio (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Conference report
    Open Access
    Problems with some sort of divergence constraint are found in many disciplines: computational fluid dynamics, linear elasticity and electrostatics are examples thereof. Such a constraint leads to a Poisson equation which ...
