      In this work, we extend the Particle Finite Element Method (PFEM) to multi-fluid flow problems with the aim of exploiting the fact that Lagrangian methods are specially well suited for tracking interfaces. We develop a ...
    • Flow behaviour of negatively buoyant jets in immiscible ambient fluid 

      Geyer Traver, Adelina; Phillips, Jeremy C.; Mier Torrecilla, Mónica de; Idelsohn Barg, Sergio Rodolfo; Oñate Ibáñez de Navarra, Eugenio (2012-01)
      Article

      In this paper we investigate experimentally the injection of a negatively buoyant jet into a homogenous immiscible ambient fluid. Experiments are carried out by injecting a jet of dyed fresh water through a nozzle in the ...
    • Numerical simulation of multi-fluid flows with the Particle Finite Element Method 

      Mier Torrecilla, Mónica de (Universitat Politècnica de Catalunya, 2010-06-29)
      Doctoral thesis
      Open Access
      La presencia simultánea de múltiples fluidos con diferentes propiedades ocurre en numerosos problemas medioambientales, procesos industriales y situaciones de la vida diaria. Algunos ejemplos son la interacción fluido-combustible ...
    • Numerical simulation of multifluid flows with the particle finite element method 

      Mier Torrecilla, Mónica de; Idelsohn Barg, Sergio Rodolfo; Oñate Ibáñez de Navarra, Eugenio (International Centre for Numerical Methods in Engineering (CIMNE), 2010)
      Book
      Open Access
      In this monograph we have focused on understanding the basic physical principles of multi-fluid flows and the difficulties that arise in their numerical simulation. We have extended the Particle Finite Element Method to ...
    • Numerical simulations of negatively buoyant jets in an immiscible fluid using the Particle Finite Elemept Method 

      Mier Torrecilla, Mónica de; Geyer Traver, Adelina; Phillips, Jeremy C.; Idelsohn Barg, Sergio Rodolfo; Oñate Ibáñez de Navarra, Eugenio (2012-06)
      Article
      Open Access
      Negatively buoyant jets consist in a dense fluid injected vertically upward into a lighter ambient fluid. The numerical simulation of this kind of buoyancy-driven flows is challenging as it involves multiple fluids with ...
    • The particle finite element method for multi-fluid flows 

      Idelsohn Barg, Sergio Rodolfo; Mier Torrecilla, Mónica de; Martí, Julio Marcelo; Oñate Ibáñez de Navarra, Eugenio (Springer, 2011)
