      Jafari, Seid Mahdi; Sohrabi, Shahin; Kebriaee, Azadeh (Universitat Politècnica de València, 2017)
      Conference report
      Restricted access - publisher's policy
      A predictive model is proposed to determine the droplet size and velocity distribution at the beginning of the secondary breakup. Liquid bulk is subjected to three stages of atomization including flow inside the injector, ...
    • A numerical study of liquid atomization regimes by means of conservative level-set simulations 

      Schillaci, Eugenio; Antepara Zambrano, Óscar; Balcázar Arciniega, Néstor; Rigola Serrano, Joaquim; Oliva Llena, Asensio (Elsevier, 2019-01-30)
      Article
      Open Access
      In this work, a conservative level-set finite-volume solver for interface-capturing is employed to perform the direct numerical simulation of Liquid Jets discharging into a quiescent air chamber. The scope is to propose a ...

    • Atomization of liquids by a novel technique 

      Guallarte Jurado, Marta (Universitat Politècnica de Catalunya / Technische Universität Graz, 2013)
      Bachelor thesis
      Restricted access - author's decision
      The usefulness of sprays in a wide range of industrial applications (combustion, coating, spray drying, etc.) makes the understanding of the atomization process very valuable, specially to choose the most suitable atomizer ...
    • Combustion of a spray atomized by a simplex 

      Lozano Torres, Noelia (Universitat Politècnica de Catalunya / Université Henri Poincaré, 2009)
      Master thesis (pre-Bologna period)
      Restricted access - author's decision
      This project is based on the study of the combustion of a mist of droplets generated by a pressure swirl nozzle (simplex). There will be realized a simulation of the injected droplets trajectories, by means of a computational ...

      Master thesis (pre-Bologna period)
      Restricted access - author's decision
      This study is devoted to the investigation of impact of a paint drop onto a thin liquid film. In particular the mechanism of bubble entrapment during drop impact will be studied. The study is motivated by the technology ...
    • Optical study of transcritical n-heptane injection under non-reacting and reacting environments 

      Escofet Martín, David; Carreres Talens, Marcos; Payri Marín, Raúl
      Conference lecture
      Restricted access - publisher's policy
      A fundamental understanding of atomization, vaporization, and mixing under transcritical conditions still needs to be accomplished [1]. In this work, we perform optical measurements at high repetition rates (¿50000 fps) ...
