  • A linear mass spectrometer by induced Hall potential for electromagnetic isotopic separation working at high pressures 

    Arias Montenegro, Francisco Javier; Parks, Geoffrey T. (2016-08-14)
    Article
    Accés restringit per política de l'editorial
    In this paper a novel alternative for bulk electromagnetic separation working at high pressures is proposed. It is shown that if a self-induced Hall potential is stimulated in the boundaries, the system will be able to ...
  • Efectos de la obstrucción del flujo en una turbina 

    Fontanals García, Alfred; Pijoan Fusté, Roger; Guardo Zabaleta, Alfredo de Jesús; Coussirat Núñez, Miguel Gustavo (Asociación Argentina de Mecánica Computacional, 2016)
    Text en actes de congrés
    Accés obert
    El rendimiento de una turbina, está sujeto al comportamiento del flujo a través de las directrices del distribuidor y de los álabes del rodete. Para evitar que el flujo de agua procedente del embalse introduzca cuerpos ...
  • Numerical simulation of added mass effects on a hydrofoil in cavitating flow using acoustic FSI 

    Liu, Xin; Zhou, Lingjiu; Wang, Zhengwei; Escaler Puigoriol, Francesc Xavier; Luo, Yongyao; Torre Rodríguez, Oscar de la (2016-11-14)
    Article
    Accés restringit per política de l'editorial
    A fluid-structure interaction system has been solved using the coupled acoustic structural finite element method to simplify the cavitating flow conditions around a hydrofoil. The modes of vibration and the added mass ...
  • Experimental and numerical analysis of directional added mass effects in partially liquid-filled horizontal pipes 

    Escaler Puigoriol, Francesc Xavier; Torre Rodríguez, Oscar de la; Goggins, Jamie (2017-02)
    Article
    Accés restringit per política de l'editorial
    The change of pipe natural frequencies due to added mass effects has been investigated in two cylindrical horizontal pipes from empty to completely water filled cases with various intermediate partially-filled conditions. ...

  • The behavior of radiogenic particles at solidification fronts 

    Arias Montenegro, Francisco Javier; Parks, Geoffrey T. (Elsevier, 2016-12-20)
    Article
    Accés restringit per política de l'editorial
    The thermal behavior of insoluble radiogenic particles at the solid-liquid interface of an advancing solidification front and its significance with regard to environmental impact are discussed. It is shown that, unlike ...
  • Numerical simulation of cavitation-erosion on a plane-convex hydrofoil using a homogeneous mixture assumption 

    Hidalgo, V.; Luo, Xianwu; Escaler Puigoriol, Francesc Xavier; Valencia, E.; Cando, E.; Yang, D. (2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    A better understanding of the cavitation-erosion mechanism is important to improve the prediction of the affected region under unsteady cavitation condition. For that, a new model has been proposed to estimate the microjet ...
  • On the use of thermal conductive focusing for solar concentration enhancement 

    Arias Montenegro, Francisco Javier (2016-10)
    Article
    Accés restringit per política de l'editorial
    We discuss the possibility for solar concentration enhancement via conductive heat transport. Here, we are concerned, as in orthodox approaches, about maximizing the solar concentration to obtain the highest receiver ...
  • A neutron diode for subcritical multistage multipliers with special reference in tritium breeding 

    Arias Montenegro, Francisco Javier; Parks, Geoffrey T (2016-04)
    Article
    Accés restringit per política de l'editorial
    In this paper the interaction between a magnetic field and the neutron spin magnetic moment is explored for use in the design of a neutron diode or valve that allows a neutron flux to pass in one direction, while preventing ...
  • On the use of encapsulated phase change materials pebbles and pellets as freeze protection method for low-stature plants/crops 

    Arias Montenegro, Francisco Javier (Elsevier, 2016-07)
    Article
    Accés restringit per política de l'editorial
    The use of phase change materials (PCMs) in encapsulated pebbles or pellets as freeze protection method for low-stature plants/crops is proposed and discussed at the conceptual level. Utilizing a simplified geometrical ...
