    • Axisymmetric vibrations of a circular Chladni plate in air and fully submerged in water 

      Escaler Puigoriol, Francesc Xavier; De la Torre Rodriguez, Oscar (2018-10-10)
      Article
      Restricted access - publisher's policy
      In this study, experimental and numerical analyses were performed to determine the effects of water loading on the axisymmetric modes of vibration of a circular plate. The plate was harmonically excited at its centre through ...
    • Dynamic response of a NACA0009 hydrofoil under cavitation conditions 

      Escaler Puigoriol, Francesc Xavier; De la Torre Rodriguez, Oscar (2018)
      Conference report

      The dynamic response of an hydraulic machine is greatly affected by the water due to the added mass effect . However, the presence of cavitation can change the modal response of the coupled fluid - structure system because ...
    • Experimental mode shape determination of a cantilevered hydrofoil under different flow conditions 

      De la Torre Rodriguez, Oscar; Escaler Puigoriol, Francesc Xavier; Egusquiza Estévez, Eduard; Farhat, Mohamed (2016-12-01)
      Article
      Open Access
      The first three mode shapes of a cantilevered NACA0009 hydrofoil were experimentally investigated in air and under different flow conditions in a cavitation tunnel. First and second bending modes and first torsion mode ...
    • Experimental study of the dynamic response of partially filled pipes focused on natural frequencies and mode shapes 

      De la Torre Rodriguez, Oscar; Escaler Puigoriol, Francesc Xavier; Goggins, Jamie (American Society of Mechanical Engineers (ASME), 2017)
      Conference report
      Restricted access - publisher's policy
      The presence of air in piping systems is a major concern in the industry. Problems like flow disruption, reduction of hydraulic machinery efficiencies or a significant drop in pipe capacity are many times related to this ...
    • Review of parameters influencing the structural response of a submerged body under cavitation conditions 

      Escaler Puigoriol, Francesc Xavier; De la Torre Rodriguez, Oscar; Farhat, Mohamed (Institute of Physics (IOP), 2015)
      Conference report
      Open Access
      Submerged structures that operate under extreme flows are prone to suffer large scale cavitation attached to thei r surfaces. Under such conditions the added mass effects differ from the expected ones in pure liquids. ...
