    • A level-set method for thermal motion of bubbles and droplets 

      Balcázar Arciniega, Néstor; Oliva Llena, Asensio; Rigola Serrano, Joaquim (Institute of Physics (IOP), 2016)
      Text en actes de congrés
      Accés obert
      A conservative level-set model for direct simulation of two-phase flows with thermocapillary effects at dynamically deformable interface is presented. The Navier-Stokes equations coupled with the energy conservation equation ...

    • Benchmark cases for a multi-component Lattice–Boltzmann method in hydrostatic conditions 

      Puig Montellà, Eduard; Chareyre, Bruno; Salager, Simon; Gens Solé, Antonio (Springer, 2020-10)
      Article
      Accés obert
      Hydrostatic properties of partially saturated granular materials at the pore scale are evaluated by the lattice Boltzmann method (LBM) using Palabos implementation of the multi-component multiphase Shan-Chen model. Benchmark ...

    • DNS of thermocapillary migration of a bi-dispersed suspension of droplets 

      Balcázar Arciniega, Néstor; Rigola Serrano, Joaquim; Oliva Llena, Asensio (Springer, 2023)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The multiple markers unstructured conservative level-set method for two-phase flow with variable surface tension is applied in the Direct Numerical Simulation of thermocapillary-migration of a bi-dispersed suspension of ...

    • Experimental and theoretical study of the capillary effect on the mechanical behaviour of granular media 

      Moure i Foraster, Carla (Universitat Politècnica de Catalunya, 2012-06-29)
      Tesina
      Accés obert
      [ANGLÈS] Effective stress in unsaturated soils has never been physically or mathematically defined. It is still the topic in large discussions and debates in the soil mechanics community. We therefore tried to obtain a ...

    • Multilevel passive microfluidics for electrochemical biosensors 

      Azizian, Pooya; Ortega Novillo, Adrián; Ricart Campos, Jordi; Casals Terré, Jasmina; Cabot, Joan Marc (2020)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      Herein, we present a proof-of-concept 3D (multilevel) passive microfluidic device for point-of-care applications including electrochemical biosensors. Multiphase flow (air-water interface) within multilevel microchannels ...

    • Numerical simulation of non-adiabatic capillary tubes. Special emphasis on the near-saturation zone 

      Ablanque Mejía, Nicolás; Oliet Casasayas, Carles; Rigola Serrano, Joaquim; Oliva Llena, Asensio (Elsevier, 2015-04-15)
      Article
      Accés obert
      The aim of this article is to present a distributed numerical model that simulates the thermal and fluid-dynamic phenomena inside non-adiabatic capillary tubes. The resolution approach is based on a two-phase flow model ...

    • Optimización de un medio filtrante que permita el uso directo de agua marina en sistemas de riego 

      García Raurich, Josep; Cusidó Lombera, Crisant; Monagas Asensio, Pedro; Arnal Madrid, Oriol; Badrena Massó, Àlex (Ediciones Pirámide (Grupo Anaya S.A.), 2019)
      Capítol de llibre
      Accés restringit per política de l'editorial
      Basándose en la experiencia acumulada sobre la viabilidad de la utilización del agua marina como aporte subterráneo de humedad y nutrientes mediante irrigación por capilaridad, se propone un medio filtrante formado ...

    • 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 ...
