  • Numerical investigation into the influence on hydrofoil vibrations of water tunnel test section acoustic modes 

    Wang, Wei; Zhou, Lingjiu; Wang, Zhengwei; Escaler Puigoriol, Francesc Xavier; De La Torre, Oscar (2019-06-17)
    Article
    Restricted access - publisher's policy
    High-speed water tunnels are typically used to investigate the single-phase and two-phase flows around hydrofoils for hydraulic machinery applications but their dynamic behavior is not usually evaluated. The modal analysis ...
  • Gas film heat transfer as enhancement strategy for phase change materials 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (Wiley (John Wiley & Sons), 2019-10-16)
    Article
    Restricted access - publisher's policy
    In this work, consideration is given to an alternative strategy for phase change materials (PCMs) heat transfer enhancement with particular reference to horizontal plates. In contrast with current approaches in which heat ...
  • On the feasibility of ocean brine pool power stations 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (2019-10-22)
    Article
    Restricted access - publisher's policy
    The demonstrated existence of vast brine pools in a number of places in the ocean basin around the world offers an interesting opportunity to the production of power from ocean, which has not been yet considered. The ...
  • A review of gerotor technology in hydraulic machines 

    Gámez Montero, Pedro Javier; Codina Macià, Esteban; Castilla López, Roberto (2019-06-24)
    Article
    Open Access
    Over the years, numerous investigations have established the gerotor fundamentals. This work aims to provide a complete review of the literature from the last decade, focusing on the articles published in the past five ...
  • 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 ...
