    Article
    Accés restringit per política de l'editorial
    Due to its potential toxic properties, metal mobilization is of major concern in areas surrounding Pb-Zn mines. In the present study, metal contents and toxicity of soils, water extracts from soils, and mine drainage waters ...
  • The brinesiphon: a homolog of the thermosiphon driven by induced salinity and downward heat transfer 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (2017-09-01)
    Article
    Accés restringit per política de l'editorial
    The basis of a novel method for passive solar water heating homologous to the thermosiphon but driven by induced salinity, which causes a fluid to circulate without the need for a mechanical pump and with inverse natural ...
  • Simulation model to find the best comfort, energy and cost scenarios for building refurbishment 

    Fonseca Casas, Antoni; Ortiz, Joana Aina; Garrido Soriano, Núria; Fonseca Casas, Pau; Salom Tormo, Jaume (2017-05-12)
    Article
    Accés restringit per política de l'editorial
    This article proposes a methodology to assess building behaviour, whilst taking its life cycle into account. Understanding of the system can be obtained by combining well-known energy consumption calculation engines (TRNSYS) ...
  • Experimental study on the impulsion port of a trochoidal wheeled pump 

    Raush Alviach, Gustavo Adolfo; Gámez Montero, Pedro Javier; Castilla López, Roberto; Codina Macià, Esteban (2017-06-01)
    Article
    Accés restringit per política de l'editorial
    All positive displacement pumps produce a pulsating flow. The present paper reports the experimental measurement of steady flow pulsations in the outlet of the internal wheeled pump. In the measured flow, the manufacturing ...
  • Use of hydrodynamic cavitation for volatile removal compound 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (2017-05-18)
    Article
    Accés restringit per política de l'editorial
    Hydrodynamic cavitation and its feasibility for volatile compound removal in enclosed channels is discussed in this paper. Very high Reynolds numbers are needed to rupture liquid by decreasing its pressure below its saturated ...
  • Accurate determination of the frequency response function of submerged and confined structures by using PZT-patches 

    Presas Batlló, Alexandre; Valentín Ruiz, David; Egusquiza Estévez, Eduard; Valero Ferrando, M.del Carmen; Egusquiza Montagut, Mònica; Bossio, Matias (2017-03-22)
    Article
    Accés obert
    To accurately determine the dynamic response of a structure is of relevant interest in many engineering applications. Particularly, it is of paramount importance to determine the Frequency Response Function (FRF) for ...
  • GeroMAG: in-house prototype of an innovative sealed, compact and non-shaft-driven gerotor pump with magnetically-driving outer rotor 

    Gámez Montero, Pedro Javier; Castilla López, Roberto; Codina Macià, Esteban; Freire Venegas, Francisco Javier (2017-03-26)
    Article
    Accés obert
    The technology of gerotor pumps is progressing towards cutting-edge applications in emerging sectors, which are more demanding for pump performance. Moreover, recent environmental standards are heading towards leakage-free ...
  • Study of available turbulence and cavitation models to reproduce flow patterns in confined flows 

    Coussirat Núñez, Miguel Gustavo; Moll, Flavio; Cappa, E. Franco; Fontanals García, Alfred (2016-09)
    Article
    Accés restringit per política de l'editorial
    Cavitating flow in nozzles is a complex flow which implies a highly turbulent two-phase one. An accurate simulation which improves some numerical results found in the literature was achieved by means of an extensive ...
  • Numerical study of the aerodynamics of sound sources in a bass-reflex port 

    García Alcaide, V. M.; Pallejà Cabré, S.; Castilla López, Roberto; Gámez Montero, Pedro Javier; Romeu Garbí, Jordi; Pàmies Gómez, Teresa; Amate, Joan; Milán, Natalia (Engineering Applications of Computational Fluid Mechanics, 2017-01-20)
    Article
    Accés obert
    The aim of this paper is to study the aerodynamics phenomena of a bass-reflex port that causes noise in the audible frequency range. After discarding structural and mechanical vibration issues, the hypothesis considered ...
  • Numerical study of impingement location of liquid jet poured from a tilting ladle with lip spout 

    Castilla López, Roberto; Gámez Montero, Pedro Javier; Raush Alviach, Gustavo Adolfo; Khamashta Shahin, Munir Andrawes; Codina Macià, Esteban (2017-04)
    Article
    Accés obert
    A new approach for simulating liquid poured from a tilting lip spout is presented, using neither a dynamic mesh nor the moving solid solution method. In this case only the tilting ladle is moving, so we propose to rotate ...
