    • Parallel multigrid algorithms for computational fluid dynamics and heat transfer 

      Soria Guerrero, Manel (Universitat Politècnica de Catalunya, 2000-07-18)
      Tesi
      Accés obert
      The main purpose of the dissertation is to contribute to the development of numerical techniques for computational heat transfer and fluid flow, suitable for low cost (loosely coupled) parallel computers. It is focused on ...
    • Parameter-free modelling of a turbulent differentially heated cavity with Rayleigh number up to 10e11 

      Trias Miquel, Francesc Xavier; Soria Guerrero, Manel; Gorobets, Andrei; Verstappen, R.W.C.P. (2009-09-14)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      Since direct numerical simulations of natural convection in a differentially heated cavity cannot be performed at high Rayleigh numbers, a dynamically less complex mathematical formulation is sought. In the quest for such ...
    • Parameter-free symmetry-preserving regularization modeling of a turbulent differentially heated cavity 

      Trias Miquel, Francesc Xavier; Verstappen, R.W.C.P.; Gorobets, Andrei; Soria Guerrero, Manel; Oliva Llena, Asensio (2010-06-23)
      Article
      Accés restringit per política de l'editorial
      Since direct numerical simulations of buoyancy driven flows cannot be computed at high Rayleigh numbers, a dynamically less complex mathematical formulation is sought. In the quest for such a formulation, we consider ...

      Trias Miquel, Francesc Xavier; Verstappen, R.W.C.P.; Soria Guerrero, Manel; Oliva Llena, Asensio (2009)
      Text en actes de congrés
      Accés obert
      Since direct numerical simulations of natural convection flows cannot be performed at high Ra-numbers, a dynamically less complex mathematical formulation is sought. In the quest for such a formulation, we consider ...
    • Towards a quantitative understanding of Robert's Rising Thermal Bubble as a benchmark for 3D atmospheric codes 

      Andrés Carcasona, Marc; Soria Guerrero, Manel; García Melendo, Enrique José; Miró Jané, Arnau (American Meteorological Society, 2023-02-01)
      Article
      Accés obert
      Robert’s rising thermal bubble (RRTB) is a benchmark case used to assess atmospheric models. In this paper, RRTB is further studied both using an analytical and a numerical approach, improving to a greater extent the ...
    • Turbulent flow around a wall-mounted cube: direct numerical simulation and regularization modelling. 

      Trias Miquel, Francesc Xavier; Gorobets, Andrei; Verstappen, R.W.C.P.; Soria Guerrero, Manel; Oliva Llena, Asensio (2009)

      Accés restringit per política de l'editorial
      Since direct numerical simulation (DNS) cannot be performed at high Reynolds number, a dynamically less complex mathematical formulation is sought. In the quest for such formulation, we consider regularization (smooth ...
    • Turbulent natural convection in an open cavity: a numerical study 

      Chiva Segura, Jorge; Soria Guerrero, Manel; Oliva Llena, Asensio; Lehmkuhl Barba, Oriol (2009)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      In this paper three-dimensional turbulent natural convection heat transfer in a simplified solar receiver open cavity is studied. Smagorinsky-LES (Large Eddy Simulation) model is chosen for turbulence flow computation. The ...
    • Tychonis: a model-based approach to define and search for geometric events in space 

      Llopis, Marcel; Soria Guerrero, Manel; Franch Gutiérrez, Javier (2021-06)
      Article
      Accés obert
      Space missions need software in order to be aware of the occurrence of geometric events in different phases of their project lifecycle. However, current software packages that provide capabilities to search for geometric ...
