  • 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 ...
  • 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 ...
  • Air recovery assessment on high-pressure pneumatic systems 

    Trujillo, J. A.; Gámez Montero, Pedro Javier; Codina Macià, Esteban (2016-05-23)
    Article
    Accés obert
    A computational simulation and experimental work of the fluid flow through the pneumatic circuit used in a stretch blow moulding machine is presented in this paper. The computer code is built around a zero-dimensional ...
  • An empirical methodology for prediction of shape and flow rate of a free-falling non-submerged liquid and casting iron stream 

    Gámez Montero, Pedro Javier; Castilla López, Roberto; Freire Venegas, Francisco Javier; Khamashta Llorens, Maria; Codina Macià, Esteban (2016-09-19)
    Article
    Accés obert
    The work presented in this article demonstrates the use of an empirical and simplified approach based on an optical technique and a home-made ad hoc code that give knowledge of the shape and falling velocity of a free-falling ...
  • Three-dimensional numerical simulation of an external gear pump with decompression slot and meshing contact point 

    Castilla López, Roberto; Gámez Montero, Pedro Javier; Campo Sud, David del; Raush Alviach, Gustavo Adolfo; García Vilchez, Mercedes; Codina Macià, Esteban (2015-04-01)
    Article
    Accés restringit per política de l'editorial
    Recently several works have been published on numerical simulation of an external gear pump (EGP). Such kinds of pumps are simple and relatively inexpensive, and are frequently used in fluid power applications, such as ...
  • Computational fluid dynamics and particle image velocimetry assisted design tools for a new generation of trochoidal gear pumps 

    García Vilchez, Mercedes; Gámez Montero, Pedro Javier; Codina Macià, Esteban; Castilla López, Roberto; Raush Alviach, Gustavo Adolfo; Freire Venegas, Francisco Javier; Río Cano, Carlos (2015)
    Article
    Accés obert
    Trochoidal gear pumps produce significant flow pulsations that result in pressure pulsations, which interact with the system where they are connected, shortening the life of both the pump and circuit components. And this ...
