      Article
      Accés restringit per política de l'editorial
      The numerical analysis of an external gear pump with cavitation effects has been validated with experimental data obtained by applying Time-Resolved Particle Image Velocimetry. The effect of inlet and outlet pressure on ...
    • Pressure-drop coefficients for cushioning system of hydraulic cylinder with grooved piston: a computational fluid dynamic simulation 

      Castilla López, Roberto; Alemany, Ignasi; Algar, Antonio; Gámez Montero, Pedro Javier; Roquet, Pedro; Codina Macià, Esteban (2017-10-25)
      Article
      Accés obert
      Cushioning is an important aspect in hydraulic cylinder performance. The piston has to be decelerated before it strikes the end cap in order to avoid stresses in the cylinder components and reduce vibration that can be ...
    • Promoting lab engagement in experimental compressible flow modelling 

      Armengol Sans, Sílvia; Raush Alviach, Gustavo Adolfo; Gámez Montero, Pedro Javier (Universitat Politècnica de Catalunya, 2022-09)
