    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

    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 ...
  • Methodology based on best practice rules to design a new-born trochoidal gear pump 

    Gámez Montero, Pedro Javier; Castilla López, Roberto; Codina Macià, Esteban (2017-02-10)
    Article
    Accés obert
    The trochoidal gear pump, also known as gerotor, owing to its remarkable advantages compared to other hydraulic pumps is chosen for many engineering applications. As each application is unique, the designer ought to be ...
  • Rotor spinning transfer channel design optimization via computational fluid dynamics 

    Huiting, Lin; Bergadà Granyó, Josep Maria; Yongchun, Zeng; Nicholus T, Akankwasa; Yuze, Zhang; Jun, Wang (2017-03-16)
    Article
    Accés obert
    The conventional rotor spinning unit generates flow vortices in the transfer channel upstream region which affect the fiber configuration and consequently yarn properties. Geometry and spinning parameters such as transfer ...
  • Hemodynamics in the thoracic aorta using OpenFOAM: 4D PCMRI versus CFD
