  • Effect of rotor spinning transfer channel modification on fiber orientation and yarn properties 

    Lin, Huiting; Akankwasa, Nicholus Tayari; Bergadà Granyó, Josep Maria; Wang, Jun (2018-11-07)
    Article
    Accés restringit per política de l'editorial
    The vortices are generated at the conventional transfer channel, having adverse effects on fiber configuration. In a former research, a conventional transfer channel was modified via rounding the transfer channel inlet ...
  • Axisymmetric vibrations of a circular Chladni plate in air and fully submerged in water 

    Escaler Puigoriol, Francesc Xavier; De La Torre, Oscar (2018-10-10)
    Article
    Accés restringit per política de l'editorial
    In this study, experimental and numerical analyses were performed to determine the effects of water loading on the axisymmetric modes of vibration of a circular plate. The plate was harmonically excited at its centre through ...
  • CFD study of the supercritical transesterification of triolein: Wall-to-fluid/ particle-tofluid transport effects 

    Mekala, Samuel Jedidiah; Fontanals García, Alfred; Guardo Zabaleta, Alfredo de Jesús (2019-01)

  • A simplified methodology to evaluate the design specifications of hydraulic components 

    Roquet, Pedro; Gámez Montero, Pedro Javier; Castilla López, Roberto; Raush Alviach, Gustavo Adolfo; Codina Macià, Esteban (Multidisciplinary Digital Publishing Institute, 2018-09-11)
    Article
    Accés obert
    The fatigue of a hydraulic component inherently varies due to various factors that can be divided into two categories: structural and load spectrum variability. The effects of both variabilities must be considered when ...
  • Ferrohydrodynamic capillary convection 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (2018-09-30)
    Article
    Accés restringit per política de l'editorial
    In this work consideration is given to capillary convection on ferrofluids owing to the concentration gradient generated when a non-homogeneous magnetic field is applied. It is known that mass transfer along an interface ...
  • Numerical study on the dynamic behavior of a francis turbine runner model with a crack 

    Zhang, Ming; Valentín Ruiz, David; Valero Ferrando, Ma. del Carmen; Egusquiza Montagut, Mònica; Zhao, Weiqiang (2018-01-01)
    Article
    Accés obert
    Crack appearance in the blade is the most common type of fatigue damage in Francis turbines. However, it is sometimes difficult to detect cracks in time using the current monitoring system, even when they are very large. ...
  • On resuspension and control of reservoir sediments by surface waves and point absorbers 

    Arias Montenegro, Francisco Javier (Elsevier, 2018-07-27)
    Article
    Accés restringit per política de l'editorial
    Consideration is given to a novel approach for resuspension and control of sediment in reservoirs which nowadays and after more than six decades of research remains as the most serious technical problem faced by dam industry. ...
  • On osmotic heat engines driven by thermal precipitation-dissolution of saturated aqueous solutions 

    Arias Montenegro, Francisco Javier (2018-11)
    Article
    Accés restringit per política de l'editorial
    Cyclic thermal precipitation and dissolution of saturated aqueous solutions and its significance with regard to osmotic heat engines (OHEs) is discussed. Here, the thermal dependence of the solubility is harnessed by ...
  • Distributing the global carbon budget with climate justice criteria 

    Alcaraz Sendra, Olga; Buenestado Caballero, Pablo; Escribano Rodríguez de Robles, Beatriz; Sureda Carbonell, Bàrbara; Turon Florenza, Albert; Xercavins, Josep (2018-05-28)
    Article
    Accés restringit per política de l'editorial
    In this paper, a model for the distribution of the Global Carbon Budget between the countries of the world is presented. The model is based on the criteria of equity while also taking into account the different historical ...
  • Driving mechanisms and streamwise homogeneity in molecular dynamics simulations of nanochannel flows 

    Bitrian Varea, Vicente; Principe, Ricardo Javier (2018-01-12)
    Article
    Accés obert
    In molecular dynamics simulations, nanochannel flows are usually driven by a constant force, that aims to represent a pressure difference between inlet and outlet, and periodic boundary conditions are applied in the ...
  • Pressure retarded osmosis thermosyphon 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (2018-10)
    Article
    Accés restringit per política de l'editorial
    The basis of a novel method for passive solar water heating homologous to the thermosyphon but driven by induced salinity which circulates a fluid without the necessity of a mechanical pump and with inverse natural convection ...
  • Real-time seismic data from the bottom sea 

    Roset Juan, Francesc Xavier; Trullols Farreny, Enric; Artero Delgado, Carola; Prat Farran, Joana d'Arc; Río Fernandez, Joaquín del; Massana Hugas, Immaculada; Carbonell Ventura, Montserrat; Toma, Daniel (Multidisciplinary Digital Publishing Institute (MDPI), 2018-04-08)
    Article
    Accés obert
    An anchored marine seismometer, acquiring real-time seismic data, has been built and tested. The system consists of an underwater seismometer, a surface buoy, and a mooring line that connects them. Inductive communication ...
