  • An estimate for thermal osmotic heat storage using precipitation of common salts 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (2019-09-09)
    Article
    Restricted access - publisher's policy
    In this brief note, a first assessment on the possibilities for thermal osmotic storage by harnessing the thermal dependence of the solubility of common salts as an alternative method to sensible heat storage is discussed. ...
  • The use of compliant surfaces for harvesting energy from water streams 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (2019-09-13)
    Article
    Restricted access - publisher's policy
    The possibility for hydrokinetic energy harvesting from small water streams by using compliant surfaces is considered. The basis of the proposed idea is the deliberate bifurcation of a water stream into two streams separated ...
  • On osmotic heat powered cycles driven by thermal saturation-precipitation of aqueous solutions 

    Arias Montenegro, Francisco Javier (2019-08-09)
    Article
    Restricted access - publisher's policy
    The basis of a novel concept for osmotic heat powered cycles driven by the thermal dependence of the solubility of aqueous solutions inducing the continuous thermal precipitation/dissolution of solute is outlined. In this ...
  • A first estimate for thermal osmotic long storage 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (2019-09-15)
    Article
    Restricted access - publisher's policy
    In this brief note, a first assessment on the possibilities for thermal osmotic storage using the thermal precipitation of aqueous solutions as alternative to sensible heat storage is performed. In a recent study it was ...
  • Added mass effects on a Francis turbine runner with attached blade cavitation 

    Huang, Xingxing; Escaler Puigoriol, Francesc Xavier (Multidisciplinary Digital Publishing Institute (MDPI), 2019-06-11)
    Article
    Open Access
    To have a safe structural design, an analysis of the dynamic behavior of a Francis turbine runner with consideration of the added mass e ects of surrounding water is necessary during design phase. Both in design and at o ...
  • The lid-driven right-angled isosceles triangular cavity flow 

    An, Bo; Bergadà Granyó, Josep Maria; Mellibovsky Elstein, Fernando (2019-09-25)
    Article
    Restricted access - publisher's policy
    We employ lattice Boltzmann simulation to numerically investigate the two-dimensional incompressible flow inside a right-angled isosceles triangular enclosure driven by the tangential motion of its hypotenuse. While the ...
  • Slingshot resonance for ocean wave energy conversion 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (Springer, 2019-06-13)
    Article
    Restricted access - publisher's policy
    The slingshot effect and its application to converting ocean wave energy are discussed. It is shown that, owing to the large inertia transported by ocean waves and their periodicity, the slingshot effect can result in the ...
  • Hydrokinetic energy conversion using compliant surfaces 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (2019-05-21)
    Article
    Restricted access - publisher's policy
    In this work, consideration is given for a novel technology based on the use of compliant surfaces (membranes) for hydrokinetic energy conversion (HEC) from residual waters where the use of traditional turbines is either ...
  • Solar thermal panels for small-medium scale air cleaners in major cities 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (2019-03-01)
    Article
    Restricted access - publisher's policy
    Air quality in major cities is reaching worrisome levels across the planet owing to large-scale industrialization. As a result, air purification systems are becoming a fertile and emerging field for research. Here, ...
  • The Extractable hydrokinetic power from an oscillating membrane-based harvester 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (Elsevier, 2019-01-22)
    Article
    Open Access
    The extractable hydrokinetic power from an oscillating membrane in standing motion and induced by a water flow and its possible significance with regard energy harvesting is discussed. The main attractiveness of such an ...
  • Hornet Vespa velutina selective capture by air entrainmen 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (2019-06-09)
    External research report
    Open Access
    In a previous report, [1], the possibility for selective capture of Vespa velutina by the use of an air cannon was discussed. In this second report, we address the alternative possibility for selective capture of ...
  • Design of a global maximum power point tracking (GMPPT) for PV array based on precise PV shadow modem 

    García-Gutiérrez, Luis; Bressan, Michael; Jiménez, Fernando; Heras Jiménez, Salvador Augusto de las; Alonso, Corinne (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference lecture
    Open Access
    This paper presents the modeling of a photovoltaic system under complex shading conditions. The approach integrates a complete PV array with each cell modeled separately including shadow coefficients depending on a ...
