    • Modelització matemàtica i simulació de la dinàmica d'un reactor AnSBR 

      Freixas Cardona, Joan (Universitat Politècnica de Catalunya, 2016-07-11)
      Treball Final de Grau
      Accés obert
      Mathematical modeling is a process that aims to develop models that represent and adequately describe the behavior of complex systems, which are described by mathematical equations and are intended to predict what happens ...

    • Near bottom sediment dynamics on highly protected beaches 

      Antonijuan Rull, Josefina; Guillen, J.; López, Laura; Simarro Grande, Gonzalo (2011)
      Text en actes de congrés
      Accés obert
      This article presents some preliminary results of the sedimentary dynamics measured during 5 months in Barcelona city beaches (NW Mediterranean). Wave storms, resuspension events and near-bottom sediment fluxes are analyzed ...

    • Nearshore sand bars 

      Ribas Prats, Francesca; Falqués Serra, Albert; Garnier, Roland Charles (Springer International Publishing, 2017)
      Capítol de llibre
      Accés obert
      This review summarizes the morphological characteristics and dynamics of nearshore sand bars observed in the surf zone of sandy beaches worldwide, with length scales ranging from tens to hundreds of meters and time scales ...

    • Nearshore sand bars on western Mediterranean beaches 

      Ribas Prats, Francesca; Falqués Serra, Albert; Garnier, Roland Charles (Springer International Publishing, 2017)
      Capítol de llibre
      Accés obert
      This contribution reviews the existing observations of nearshore sand bars (including shoreparallel straight and crescentic bars, and transverse bars) on western Mediterranean beaches. In general, their morphological ...

    • On the physics behind coastal morphodynamic patterns 

      Ribas Prats, Francesca; Falqués Serra, Albert; de Swart, Huib E.; Dodd, Nicholas; Garnier, Roland Charles; Calvete Manrique, Daniel (2016)
      Text en actes de congrés
      Accés obert

    • Passive sedimentation control in containers using Marangoni forces 

      Arias Montenegro, Francisco Javier (2020-11)
      Article
      Accés restringit per política de l'editorial
      In this work consideration is given to a passive sedimentation control mechanism driven by Marangoni stress which is induced in enclosed geometries when their walls are deliberately lined with air-filled (or inert gas ...

    • Shoreline Sand Waves. A Nonlinear One-Line Model 

      Stephan, Volker (Universitat Politècnica de Catalunya, 2011-02-04)
      Projecte Final de Màster Oficial
      Accés obert
      The morpho-dynamic model presented in this paper finds its application in the large time and length scale prediction of wave-driven along-shore sediment transport. It employs an extended version of the well established ...

    • Solutocapillary for self-control precipitation in enclosed geometries by using microcavities 

      Arias Montenegro, Francisco Javier (2020-12)
      Article
      Accés obert
      In this work the possibility to endow enclosed geometries with a passive feedback mechanism to prevent precipitation when their walls are deliberately lined with air-filled hydrophobic microcavities is discussed

    • The coastal vulnerability of the Dniester barrier beach (Ukraine) 

      Torres Ribas, Marta (Universitat Politècnica de Catalunya, 2023-07-18)
      Projecte Final de Màster Oficial
      Accés obert
      La principal causa de inundaciones y erosión en áreas bajas, como las playas barrera, son las tormentas extremas. Además, los desafíos planteados por estos eventos se verán amplificados por el cambio climático, principalmente ...

    • Validación del PFEM en problemas de cuerpos sumergidos 

      Sancho Marín, Eliseo (Universitat Politècnica de Catalunya, 2008-09)
      Tesina
      Accés obert
      Los objetivos principales de esta tesina han sido en un primer lugar validar las mejoras introducidas recientemente en el código de cálculo del programa PFLOW, una implementación del PFEM desarrollada en CIMNE. El estudio ...

    • Velocity fluctuations and hydrodynamic diffusion in sedimentation 

      Miguel Lopez, M. Del Carmen; Pastor Satorras, Romualdo (2001-01-23)
      Article
      Accés obert
      We study non-equilibrium velocity fluctuations in a model for the sedimentation of non-Brownian particles experiencing long-range hydrodynamic interactions. The complex behavior of these fluctuations, the outcome of the ...
