  • Flexible rod design for educational wind balance 

    Raush Alviach, Gustavo Adolfo; Castilla López, Roberto; Gámez Montero, Pedro Javier; Wojciechowski, Jakub; Codina Macià, Esteban (2016-03-07)
    Article
    Accés obert
    This article provides a technical description of a flexible hinge for wind tunnel rigs. For academic purposes, the device was integrated into several rod flexures to build a home-made external wind balance system. The ...
  • Experimental study of a vibrating disk submerged in a fluid-filled tank and confined with a nonrigid cover 

    Valentín Ruiz, David; Presas Batlló, Alexandre; Egusquiza Estévez, Eduard; Valero Ferrando, M.del Carmen; Egusquiza Montagut, Mònica (2017-04-01)
    Article
    Accés restringit per política de l'editorial
    Determining the dynamic response of submerged and confined disklike structures is of interest in engineering applications, such as in hydraulic turbine runners. This dynamic response is heavily affected by the added mass ...
  • Heat removal system for shutdown in nuclear thermal rockets and advanced concepts 

    Arias Montenegro, Francisco Javier; Parks, Geoffrey T. (2017-02-09)
    Article
    Accés obert
    It is well-known that a nuclear thermal rocket (NTR) cannot be abruptly shut down. After a power manoeuver, the reactor has contaminated itself with fission products and the decay heat released must be removed by maintaining ...
  • Estimation of wall shear stress using 4D flow cardiovascular MRI and computational fluid dynamics 

    Soudah Prieto, Eduardo; Casacuberta Puig, Jordi; Gámez Montero, Pedro Javier; Raush Alviach, Gustavo Adolfo; Castilla López, Roberto (2016-10-26)
    Article
    Accés restringit per política de l'editorial
    In the last few years, wall shear stress (WSS) has arisen as a new diagnostic indicator in patients with arterial disease. There is a substantial evidence that the WSS plays a significant role, together with hemodynamic ...
  • 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 ...
  • 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. ...
  • Efectos de la obstrucción del flujo en una turbina 

    Fontanals García, Alfred; Pijoan Fusté, Roger; Guardo Zabaleta, Alfredo de Jesús; Coussirat Núñez, Miguel Gustavo (2016-11)
    Article
    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 ...
  • 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 ...
  • 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 ...
