    • Chaotic advection, transport and patchiness in clouds of pollution in an estuarine flow 

      Stirling, James Robert (American Institute of Mathematical Sciences, 2001)
      Article
      Accés obert
      We present an application of the transport theory developed for area preserving dynamical systems, to the problem of pollution and in particular patchiness in clouds of pollution in partially stratified estuaries. We ...

    • Computational of turbulent flows using a finite element formulation 

      Oñate Ibáñez de Navarra, Eugenio; Valls Tomas, Aleix; García Espinosa, Julio (2007-02)
      Report de recerca
      Accés obert
      We present a formulation for analysis of turbulent incompressible flows using a stabilized finite element method (FEM) based on the finite calculus (FIC) procedure. The stabilization terms introduced by the FIC approach ...

    • Finite element approximation of 3D non-hydrostatic turbulent coastal ocean flows using a LES model 

      Blasco Lorente, Jorge; Maidana, Manuel Augusto; German, Arnel; Espino Infantes, Manuel (2008-01-07)
      Article
      Accés obert
      In this paper we present a stabilized finite element method for three-dimensional, non-hydrostatic, turbulent coastal ocean flows. The model we have developed, named HELIKE, incorporates also surface wind stress, bottom ...

    • LES turbulence Models: relation with stabilized numerical methods 

      Valls Molina, Antonio; García Espinosa, Julio; Oñate Ibáñez de Navarra, Eugenio (2006-05)
      Report de recerca
      Accés obert
      Abstract One of the aims of this text is to show some important results in LES modelling and to identify which are main mathematical problems for the development of a complete theory. A relevant aspect of LES theory, which ...

    • Multiscale modeling of a closure problem using the scattering transform 

      Prat Colomer, Maria (Universitat Politècnica de Catalunya, 2023-05-25)
      Treball Final de Grau
      Accés obert
      Realitzat a/amb:   New York University
      Els models climàtics estimen la dinàmica dels fluids a la Terra resolent equacions contínues en quadrícules finites. Els processos físics per sota de la resolució dels models climàtics tenen efectes estadístics a les escales ...
